July 2019

 

Below are the pumping, water releases and evaporation for July 2019.  The current elevation of Lake Fork is 402.38, so the lake is 0.62 feet below full pool level of 403.  On this date last year the lake was at 401.02, so it was 1.98 feet below full pool. On this date in 2017 it was 0.69 feet below full pool.

 

Note: It is pretty amazing how fast the surface of Lake Fork shrinks as the lake goes down.  With the lake only 0.62 feet below full pool the surface area of the lake has shrunk from 27,690 acres to 25,847 acres.


Evaporation for July 2019 =  9.57 inches or about 21,290 acre-feet.  This is the equivalent of about 6.9 billion gallons of water lost by evaporation in July.


Rainfall Recorded at the SRA Headquarters for July 2019 =  0.44 inches.

Water Released for July 2019 by the SRA for Downstream Communities (including water pumped by Bright Star Salem and the City of Quitman and this also includes the water continually released through the pipes at the dam to meet the minimum flow requirements of the Sabine River Compact) = 1,231.4 acre-feet.  This equals about 0.55 inches taken off the lake in July and equals about 401 million gallons of water.  Communities receiving downstream water include Kilgore, Longview, Henderson and Texas Eastman in Longview.

So, the total amount of water removed from Lake Fork so far in 2017 is about 160,926.1 acre-feet or about 6 feet of water or about 72 inches off the lake.  About 63% of the water removed from the lake through July has been due to evaporation, while 22% has been from water released through the flood gates, 12% has been from Dallas pumping and 3% has been from releases to downstream communities.  

June 2017

 

Evaporation for June 2017 =  9.32 inches or about 21,505.9 acre-feet.  This is the equivalent of about 7 billion gallons of water lost by evaporation in June. 
 

Rainfall Recorded at the SRA Headquarters for June 2017 = 3.24 inches. 

 

Water Released for June 2017 by the SRA for Downstream Communities (including water pumped by Bright Star Salem and the City of Quitman and this also includes the water continually released through the pipes at the dam to meet the minimum flow requirements of the Sabine River Compact) = 583.1 acre-feet.  This equals about 0.25 inches taken off the lake in May and equals about 190 million gallons of water.  Communities that receive downstream water include Kilgore, Longview, Henderson and Texas Eastman in Longview.    
 

Water Pumped by Dallas for June 2017 = 5,036.2 acre-feet or about 1.64 billion gallons. This is equal to about 2.18 inches of water being removed off the surface of the lake.  

 

Water Released by the SRA through the Tainter Flood Gates for June 2017 = One or more gates were open for 3 days in June resulting in 11,260.2 acre-feet of water being spilled through the dam for 3.7 billion gallons of water.  This is equal to about 4.88 inches of water being removed off the surface of the lake.

So, the total water removed from Lake Fork for June 2017 = 38,385.4 acre-feet or about 16.6 inches of water taken off the surface of the lake.  This equals about 12.5 billion gallons of water removed from the lake during June.  About 56% of the water removed from the lake in June was due to evaporation, while about 29% was due to spillage through the gates and 13% was from Dallas pumping.  

2017 Totals Through June 2017

Evaporation for 2017 = 36.35 inches or about 3.03 feet, which equals about 83,900 acre-feet.  This equals about 27.3 billion gallons of water removed through evaporation.

Water Pumped by Dallas for April 2017 = 2,463.2 acre-feet or about 803 million gallons. This is equal to about 1 inch of water being removed off the surface of the lake.  Dallas had not pumped since January.   

Water Released by the SRA through the Tainter Flood Gates for April 2017 = One or more gates were open for 5 days in April resulting in 10,016 acre-feet of water being spilled through the dam for 3.26 billion gallons of water.  This is equal to about 4.3 inches of water being removed off the surface of the lake. 

So, the total water removed from Lake Fork for April 2017 = 27,293.1 acre-feet or about 11.8 inches of water taken off the surface of the lake.  This equals about 8.9 billion gallons of water removed from the lake during April.  About 52% of the water removed from the lake in April was due to evaporation, while about 37% was due to spillage through the gates and 9% was from Dallas pumping.  

2017 Totals Through April 2017

Evaporation for 2017 = 19.07 inches or about 1.6 feet, which equals about 44,027 acre-feet.  This equals about 14.3 billion gallons of water removed through evaporation.

Rainfall Recorded at the SRA Headquarters for 2017 = 13.83 inches.

Water Released by the SRA to Downstream Communities for 2017 = 2,217.2 acre-feet, which equals about 1 inch of water off the lake.  This equals about 722 million gallons of water released to downstream communities that have rights to the water.  

Water Pumped by Dallas for 2017 = 3,677.6 acre-feet or about 1.2 billion gallons.  This equals about 1.6 inches of water taken off the lake from Dallas pumping through April.  We are now 33% of the way through the calendar year and so far Dallas has pumped less than 3% of the water they are entitled to for the year.  
 

Water Released by the SRA through the Tainter Flood Gates in 2017 = 10,016 acre-feet has been spilled through the Tainter Flood Gates, which equals about 3.26 billion gallons of water.  This equals about 4.34 inches of water off the surface of the lake.   

 

So, the total amount of water removed from Lake Fork so far in 2017 is about 57,726.1 acre-feet or about 2.1 feet of water or about 24.6 inches off the lake.  About 76% of the water removed from the lake through April has been due to evaporation, while 17% has been from water released through the flood gates and 6% has been from Dallas pumping. 
 

Whenever the SRA spills water through the gates the question always arises as to why they cannot allow water to stack up against the gates.  The engineering design for the dam does not allow for holding water against the flood gates.  It would potentially threaten the structural integrity of the dam and would be in violation of the operating manual for the dam.  Also, Lake Fork Dam does not have an emergency spillway, so excess water has to be released through the gates.

March 2017:

Below are the pumping, water releases and evaporation for March 2017.  The current surface acres of Lake Fork is at 24,801 acres versus 27,690 acres when the lake is full.  That means we have about 2,889 acres of exposed shoreline that would be covered by water if the lake was at full pool.  The lake did come up by 85 acre-feet in the last month.  
 

Evaporation for March 2017 = 5.99 inches or about 12,380 acre-feet.  This is the equivalent of about 4 billion gallons of water lost by evaporation in March. 

Rainfall Recorded at the SRA Headquarters for March 2017 = 1.90 inches (remember this is for March, so it does not include the rain we got last weekend).

So, the total water removed from Lake Fork for March 2017 = 12,974 acre-feet or about 6.3 inches of water taken off the surface of the lake.  This equals about 4.2 billion gallons of water removed from the lake during March. 95% of that water removal was from evaporation during March. 

2017 Totals Through March 2017

Evaporation for 2017 = 12.9 inches or about 1.1 feet, which equals about 26,660 acre-feet.  This equals about 8.7 billion gallons of water removed through evaporation.

Rainfall Recorded at the SRA Headquarters for 2017 = 4.5 inches.

Water Released by the SRA to Downstream Communities for 2017 = 1,638.3 acre-feet, which equals about 0.79 inches of water off the lake.  This equals about 534 million gallons of water released to downstream communities that have rights to the water.  

Water Pumped by Dallas for 2017 = 1.214.4 acre-feet or about 395 million gallons.  This equals about 0.59 inches of water taken off the lake from Dallas pumping through March.  
 

Water Released by the the SRA through the Tainter Flood Gates = 0 acre feet so far in 2017. 

 

So, the total amount of water removed from Lake Fork so far in 2017 is about 29,433 acre-feet or about 1.19 feet of water or about 14.3 inches off the lake.  About 90.5% of that has been through evaporation so far this year. 

February 2017:

Below are the pumping, water releases and evaporation for February 2017.  The current surface acres of Lake Fork is at 24,716 acres versus 27,690 acres when the lake is full.  That means we have about 2,974 acres of exposed shoreline that would be covered by water if the lake was at full pool.  The lake did come up by 151 acre-feet in the last month.  
 

Evaporation for February 2017 = 4.27 inches or about 8,795 acre-feet.  This is the equivalent of about 2,87 billion gallons of water lost by evaporation in February. 

Rainfall Recorded at the SRA Headquarters for February 2017 = 2.60 inches. 

Water Released for February 2017 by the SRA for Downstream Communities (including water pumped by Bright Star Salem and the City of Quitman) = 455.3 acre-feet.  This equals about 0.22 inches taken off the lake in February and equals about 148 million gallons of water.  Communities that receive downstream water include Kilgore, Longview, Henderson and Texas Eastman in Longview.

So, the total water removed from Lake Fork for February 2017 = 9,250 acre-feet or 4.49 inches of water taken off the surface of the lake.  This equals about 3.014 billion gallons of water removed from the lake during February. 95% of that water removal was from evaporation during February. 

2017 Totals Through February 2017

Evaporation for 2017 = 6.91 inches or about 0.58 feet, which equals about 14,200 acre-feet.  This equals about 4.63 billion gallons of water removed through evaporation.

Rainfall Recorded at the SRA Headquarters for 2017 = 8.17 inches.

Water Released by the SRA to Downstream Communities for 2017 = 1,044.3 acre-feet, which equals about 0.51 inches of water off the lake.  This equals about 340 million gallons of water released to downstream communities that have rights to the water.  

Water Pumped by Dallas for 2017 = 1.214.4 acre-feet or about 395 million gallons.  This equals about 0.59 inches of water taken off the lake from Dallas pumping through February.  

Water Released by the the SRA through the Tainter Flood Gates = 0 acre feet so far in 2017. 

 

So, the total amount of water removed from Lake Fork so far in 2017 is about 16,459 acre-feet or about 0.67 feet of water or about 8 inches off the lake.  About 86% of that has been through evaporation so far this year.

 

January 2017
 

Evaporation for January 2017 = 2.64 inches or about 5,404 acre-feet.  This is the equivalent of about 1.76 billion gallons of water lost by evaporation in January. 

Rainfall Recorded at the SRA Headquarters for January 2017 = 5.57 inches. 

Water Released for January 2017 by the SRA for Downstream Communities (including water pumped by Bright Star Salem and the City of Quitman) = 589 acre-feet.  This equals about 0.29 inches taken off the lake in January and equals about 191 million gallons of water.

Water Pumped by Dallas for January 2017 = 1,212.4 acre-feet or about 395 million gallons.  This equals about 0.59 inches of water taken off the lake from Dallas pumping in January. 

Water Released by the SRA through the Tainter Flood Gates for January 2017 = 0 acre-feet. 
 

So, the total water removed from Lake Fork for January 2017 = 7,205.4 acre-feet or 3.52 inches of water taken off the surface of the lake.  This equals about 2.35 billion gallons of water removed from the lake during January.  

December 2016:

 

Evaporation for December 2016 = 2.41 inches or about 4861 acre-feet.  This is the equivalent of about 1.58 billion gallons of water lost by evaporation.  

Rainfall Recorded at the SRA Headquarters for December 2016 = 2.71 inches.

Water Released for December 2016 by the SRA for Downstream Communities = 1,653.8 acre-feet or about 0.82 inches off the lake.  This equals about 539 million gallons of water.

Water Pumped by Dallas for December 2016 = 7,353.8 acre-feet or about 3.65 inches of water off the lake.  This equals about 2.4 billion gallons of water pumped by Dallas in December. 

Water Released by the SRA through the Tainter Flood Gates for December 2016 = 0 acre-feet. 
 

So, the total water removed from Lake Fork for December 2016 = 13,868.6 acre feet or about 6.88 inches.  This is the first month of the year that Dallas pumping has exceeded evaporation.  This equals about 4.5 billion gallons of water removed from Lake Fork in December. 


Final 2016 Totals 

Evaporation for 2016 = 73.53 inches or about 6.13 feet, which equals about 159,000 acre-feet (this is approximate because as the lake drops the surface area shrinks).  This is equal to about 51.8 billion gallons of water leaving the lake through evaporation for calendar year 2016.

Rainfall Recorded at the SRA Headquarters for 2016 = 44.96 inches or about 3.75 feet.  

Water Released for 2016 by the SRA for Downstream Communities = 8,812.7 acre-feet or about 4.07 inches off the lake.  This equals about 2.87 billion gallons of water released to downstream communities that have rights to the water.  This includes the water diverted by Bright Star Salem and the City of Quitman. 

Water Pumped by Dallas for 2016 = 62,119.50 acre-feet or about 2.4 feet or about 28.8 inches taken off the lake by Dallas pumping.  This equals about 20.2 billion gallons of water removed though pumping by Dallas for calendar year 2016. 

Water Released by the SRA through the Tainter Flood Gates for 2016 = 290,064 acre-feet or about 10.5 feet or about 126 inches.  This represents about 94.5 billion gallons of water released through the flood gates earlier this year to protect the flood gates from over topping. 
 

So, the total amount of water removed from Lake Fork during 2016 was about 520,000 acre-feet or about 20 feet.  about 56% of that was for releases through the flood gates to protect the flood gates from over topping earlier this year.  About 31% of the water was lost through evaporation.  About 12% was removed through Dallas pumping.  
 

The 62,119.50 acre-feet pumped by Dallas actually is only about 47% of what they are entitled to take in a year.  Dallas averaged pumping about 55 million gallons per day over the entire year.  Last year (2015) Dallas pumped 57,994 acre-feet, so they continue to pump less than 50% of what they may eventually take annually.  The total water lost off the lake in 2015 was about 22 feet compared to the 20 feet in 2016. 

November 2016:

Below are the pumping, water releases and evaporation for November 2016.  It is interesting to note that the lake is now 24,230 surface acres versus 27,690 surface acres when at full pool.  That means we currently have 3,460 acres of exposed shoreline that would be under water if the lake was at full pool.  
 

Evaporation for November 2016 = 3.82 inches or about 7,713 acre-feet.  This is the equivalent of about 2.5 billion gallons of water.   

Rainfall Recorded at the SRA Headquarters for November 2016 = 3.5 inches. 

Water Releases for November 2016 by the SRA for Downstream Communities = 1,734.1 acre-feet or about 0.86 inches off the lake.  This equals about 565 million gallons of water.  

Water Pumped by Dallas for November 2016 = 6,531.9 acre-feet or about 3.24 inches off the lake.  This equals about 2.1 billion gallons of water.  

Water Released by the SRA through the Tainter Flood Gates for November 2016 = 0.0. 

So, the total water removed from the lake for November 2016 = About 7.92 inches or about 0.66 feet with slightly more from evaporation than Dallas pumping.  This equals about 15,992 acre-feet or about 5.2 billion gallons of water.  


2016 Totals through November:

Evaporation for 2016 = 70.73 inches or about 5.89 feet, which equals approximately 142,715 acre-feet (this is approximate because as the lake drops the surface area shrinks).  This is equal to about 46.5 billion gallons of water leaving the lake through evaporation.  

Rainfall Recorded at the SRA Headquarters for 2016 = 42.77 inches or about 3.56 feet.  
 

Water Released by the SRA to Downstream Communities for 2016 = 6,509 acre-feet, which equals about 3.22 inches off the lake.  This equals about 2.12 billion gallons of water released to downstream communities that have rights to the water.  

 

Water Pumped by Dallas for 2016 = 55,134 acre-feet or about 2.28 feet or about 27.4 inches taken off the lake by Dallas pumping.  This equals about 18.0 billion gallons of water removed through pumping by Dallas so far in 2016.  
 

Water Released Downstream by the SRA through the Tainter Flood Gates when the Lake was Overfull in 2016 = 290,064 acre-feet or about 10.48 feet or about 125.76 inches.  This represents 94.5 billion gallons of water.  
 

So, the total amount of water removed from the lake so far in 2016 is about 494,422 acre-feet or about 20 feet. About 59% of that was the downstream releases through the Tainter Flood Gates when the lake was overfull to prevent damage to the dam.  About 29% has been due to evaporation.  About 11% has left the lake so far in 2016 via pumping by Dallas.  
 

Dallas pumped about 1600 less acre-feet of water in November than they did in October.  They had averaged less than 6000 acre feet per month through July and then pumped very little water in August and September, but in October they pumped 8193.6 acre-feet and then 6,531.9 acre-feet in November from Lake Fork.  The total so far for the year of 55,134 acre-feet represents about 42% of the water that Dallas is entitled to pump from Lake Fork for the year yet we are now 91% of the way through the year, so it appears Dallas will not take nearly what they are entitled to pump in a year.  So far Dallas has averaged pumping about 54 million gallons of water per day in 2016. 

October 2016:
 

Evaporation for October 2016 = 6.25 inches. 

Rainfall Recorded at the SRA Headquarters for October 2016 = 1.52 inches. 

Water Releases for October 2016 by the SRA for Downstream Communities = 884.1 acre-feet or about 0.43 inches off the lake.  

Water Pumped by Dallas for October 2016 = 8,193.6 acre-feet or about 4.02 inches off the lake.  

Water Released by the SRA through the Tainter Flood Gates for October 2016 = 0.0. 

So, the total water removed from the lake for October 2016 = About 10.07 inches or about 0.89 feet with most of that still coming from evaporation, but for the first time this year pumping by Dallas was a close second. 


2016 Totals through October:

Evaporation for 2016 = 66.91 inches or about 5.58 feet, which equals approximately 139,500 acre-feet (this is approximate because as the lake drops the surface area shrinks.  Right now the lake is at 24,445 surface acres versus 27,690 surface acres at full pool). 

Rainfall Recorded at the SRA Headquarters for 2016 = 39.27 inches or about 3.27 feet.  

Water Released by the SRA to Downstream Communities for 2016 = 4,774.9 acre-feet, which equals about 2.35 inches off the lake.  This equals about 1.56 billion gallons of water released to downstream communities that have rights to the water.  

 

Water Pumped by Dallas for 2016 = 48,602.1 acre-feet or about 1.99 feet or about 23.88 inches taken off the lake by Dallas pumping.  This equals about 15.8 billion gallons of water removed through pumping by Dallas so far in 2016.  
 

Water Released Downstream by the SRA through the Tainter Flood Gates when the Lake was Overfull in 2016 = 290,064 acre-feet or about 10.48 feet or about 125.76 inches.  This represents 94.5 billion gallons of water.  
 

So, the total amount of water removed from the lake so far in 2016 is about 482,941 acre-feet or about 19.76 feet. About 60% of that was the downstream releases through the Tainter Flood Gates when the lake was overfull to prevent damage to the dam.  About 29% has been due to evaporation.  About 10% has left the lake so far in 2016 via pumping by Dallas.  
 

October was by far the most water Dallas has pumped this year.  They had averaged less than 6000 acre feet per month through July and then pumped very little water in August and September, but in October they pumped 8193.6 acre-feet from Lake Fork.  The total so far for the year of 48,602.1 acre-feet represents about 37% of the water that Dallas is entitled to pump from Lake Fork for the year yet we are now 83% of the way through the year, so it appears Dallas will not take nearly what they are entitled to pump in a year.  So far Dallas has averaged pumping about 52 million gallons of water per day in 2016.  
 

Best wishes and as usual pray/hope/dance for rain.  
 

September 2016:
 

Evaporation for September 2016 = 7.36 inches. 

Rainfall Recorded at the SRA Headquarters for September 2016 = 1.27 inches. 

Water Releases for September 2016 by the SRA for Downstream Communities = 870.9 acre-feet or about 0.42 inches off the lake.  

Water Pumped by Dallas for September 2016 = 480.6 acre-feet or about 0.233 inches off the lake.  

Water Released by the SRA through the Tainter Flood Gates for September 2016 = 0.0. 

So, the total water removed from the lake for September 2016 = About 8.01 inches or about 0.67 feet with most of that coming from evaporation.  


2016 Totals through September:

Evaporation for 2016 = 60.66 inches or about 5.06 feet, which equals approximately 129,000 acre-feet (this is approximate because as the lake drops the surface area shrinks.  Right now the lake is at 24,794 surface acres versus 27,690 surface acres at full pool). 

Rainfall Recorded at the SRA Headquarters for 2016 = 37.75 inches or about 3.15 feet.  
 

Water Released by the SRA to Downstream Communities for 2016 = 3,890.8 acre-feet, which equals about 1.88 inches off the lake.  This equals about 1.27 billion gallons of water released to downstream communities that have rights to the water.  

 

Water Pumped by Dallas for 2016 = 40,408.5 acre-feet or about 1.63 feet or about 19.56 inches taken off the lake by Dallas pumping.  This equals about 13.2 billion gallons of water removed through pumping by Dallas so far in 2016.  
 

Water Released Downstream by the SRA through the Tainter Flood Gates when the Lake was Overfull in 2016 = 290,064 acre-feet or about 10.48 feet or about 125.76 inches.  This represents 94.5 billion gallons of water.  
 

So, the total amount of water removed from the lake so far in 2016 is about 463,363 acre-feet or about 17.8 feet. About 63% of that was the downstream releases through the Tainter Flood Gates when the lake was overfull to prevent damage to the dam.  About 28% has been due to evaporation.  Less than 9% has left the lake so far in 2016 via pumping by Dallas.  
 

Amazingly Dallas continues to pump very little water from Lake Fork.  The total so far for the year of 40,408.5 acre-feet represents about 31% of the water that Dallas is entitled to pump from Lake Fork for the year yet we are now 75% of the way through the year, so it appears Dallas will not take nearly what they are entitled to pump in a year.  So far Dallas has averaged pumping about 48 million gallons of water per day in 2016.  
 

Best wishes and as usual pray/hope/dance for rain.  Actually, today we received about 1.3 inches of rain, which was a pleasant surprise. 

August 2016:


Evaporation for August = 8.48 inches 
 

Rainfall Recorded at the SRA Headquarters for August = 7.72 inches. 

Water Released for August by the SRA for Downstream Communities = 931.5 acre-feet or about 0.43 inches off the lake. 

Water Pumped by Dallas for August = 23 acre-feet or about 0.01 inches off the lake.  

Water Released by the SRA for August through the Tainter Flood Gates = 0.0 acre-feet.  

So, the total water removed from the lake for August = About 8.92 inches or about 0.75 feet with most of that coming from evaporation.  


2016 Totals through August:

Evaporation for 2016 = 52.65 inches or about 4.39 feet, which equals about 114,140 acre-feet.

Rainfall Recorded at the SRA Headquarters for 2016 = 36.48 inches or about 3.04 feet.  (Note:  3 feet of rainfall falling on the lake does not mean the lake rises 3 feet.  The lake is spreading out to a larger surface area as it rises).

Water Released by the SRA to Downstream Communities for 2016 = 3,010.9 acre-feet, which equals about 1.4 inches off the lake.  This equals about 981 million gallons of water released to downtown communities that have rights to the water.  

Water Pumped by Dallas for 2016 = 39,927.9 acre-feet or about 1.54 feet or about 18.5 inches taken off the lake by Dallas pumping.  This equals about 13 billion gallons of water removed through pumping by Dallas.

Water Released Downstream by the SRA through the Tainter Flood Gates when the Lake was overfull in 2016 = 290,064 acre-feet or about 10.48 feet or about 125.76 inches.  This represents 94.5 billion gallons of water.  

So, the total amount of water removed from the lake so far in 2016 is about 447,143 acre-feet or about 17.2 feet.  About 65% of that has been through downstream releases through the flood gates when the lake was overfull to prevent damage to the dam.  About 26% has been due to evaporation.  Less than 9% has left the lake so far in 2016 via pumping by Dallas.  

Amazingly Dallas only pumped 23 acre-feet this past month and their total for the year is now 39,927.9 acre-feet.  That represents about 30% of the water that Dallas is entitled to pump from Lake Fork for the year yet we are now 67% of the way through the year, so it appears Dallas will not take nearly what they are entitled to pump in a year.  So far Dallas has averaged pumping about 53.3 million gallons per day in 2016.

Best wishes and as usual pray/hope/dance for rain. 

July 2016: 
 

Below are the pumping, water releases and evaporation for July 2016.

Evaporation for July = 11.67 inches 

Rainfall Recorded at the SRA Headquarters for July = 1.59 inches. 

Water Released for July by the SRA for Downstream Communities = 927.7 acre-feet or about 0.43 inches off the lake. 

Water Pumped by Dallas for July = 6,389.1 acre-feet or about 2.95 inches off the lake.  

Water Released by the SRA for July through the Tainter Flood Gates = 0.0 acre-feet.  

So, the total water removed from the lake for July = About 15.05 inches or about 1.25 feet with most of that coming from evaporation.  


2016 Totals through July:

Evaporation for 2016 = 44.17 inches or about 3.68 feet, which equals about 95,680 acre-feet. 

Rainfall Recorded at the SRA Headquarters for 2016 = 28.76 inches or about 2.4 feet.  

Water Released by the SRA to Downstream Communities for 2016 = 2,079.4 acre-feet, which equals about 0.96 inches off the lake.  This equals about 678 million gallons of water released to downtown communities that have rights to the water.  

Water Pumped by Dallas for 2016 = 39,904.9 acre-feet or about 1.54 feet or about 18.5 inches taken off the lake by Dallas pumping.  This equals about 13 billion gallons of water removed through pumping by Dallas. 

Water Released Downstream by the SRA through the Tainter Flood Gates when the Lake was overfull in 2016 = 290,064 acre-feet or about 10.48 feet or about 125.76 inches.  This represents about 94.5 billion gallons of water.  

So, the total amount of water removed from the lake so far in 2016 is about 427,728.3 acre-feet or about 16.45 feet.  About 68% of that has been through downstream releases through the flood gates when the lake was overfull to prevent damage to the dam.  22% has been due to evaporation.  Only 9% left the lake via pumping by Dallas.  

Dallas Water Utilities has pumped 39,904.9 acre-feet from Lake Fork so far this year.  That represents about 30% of the water that Dallas is entitled to pump from Lake Fork in a year yet we are now 58% of the way through the year, so it appears Dallas will not take nearly what they are entitled to pump in a year.  So far Dallas has averaged pumping about 61 million gallons per day. 

June 2016:
 

Below are the pumping, water releases and evaporation for June 2016.

Evaporation for June = 8.16 inches. 

Rainfall Recorded at the SRA Headquarters for June = 3.83 inches. 

Water Released for June by the SRA for Downstream Communities = 306.9 acre-feet or about 0.133 inches off the lake.  

Water Pumped by Dallas for June = 5,795.0 acre-feet.  This equals about 2.51 inches of water taken off the lake by pumping.  

Water Released by the SRA through the Tainter Gates for June = 45,846.0 acre-feet or about 1.66 feet or 19.87 inches released through the dam when the lake was overfull.  

So, the total water removed from the lake for June = 30.67 inches or about 2.56 feet.  Please keep in mind most of this water was released when the lake was above full pool in early June.  


2016 Totals through June: 

Evaporation for 2016 = 32.5 inches or about 2.71 feet, which equals about 75,040 acre-feet.  This equals about 24.5 billion gallons lost through evaporation.  

Rainfall Recorded at the SRA Headquarters for 2016 = 27.17 inches or about 2.26 feet.

Water Released by the SRA to Downstream Communities for 2016 = 1,151.7 acre-feet, which equals about 0.50 inches of water taken off the lake.  This equals about 376 million gallons of water removed from the lake by releases downstream to communities that have rights to the water.  

Water Pumped by Dallas for 2016 = 33,515.8 acre-feet or about 1.2 feet or about 14.4 inches taken off the lake via Dallas pumping.  This equals about 10.9 billion gallons of water removed through pumping by Dallas.  

Water Released Downstream by the SRA through the Tainter Flood Gates when the Lake was Overfull in 2016 = 290,064 acre-feet or about 10.48 feet or about 125.76 inches.  This represents about 94.5 billion gallons of water.

So, the total amount of water removed from the lake so far in 2016 is about 399,777.5 acre-feet or about 14.44 feet.  About 73% has been through downstream releases through the flood gates when the lake was overfull to prevent damage to the dam.  

Dallas Water Utilities has pumped 33,515.8 acre-feet from Lake Fork so far this year.  That represents less than 26% of the water they are entitled to take from Lake Fork in a year yet we now 50% of the way through the year, so it appears Dallas will not take nearly what they are entitled to pump in a year.  So far Dallas has averaged pumping about 60 million gallons per day. 

May 2016:
 

Below are the pumping, water releases and evaporation totals for May 2016.

Evaporation for May = 6.6 inches. 

Rainfall Recorded for May at the SRA Headquarters = 1.85 inches.

Water Released Downstream for Communities by the SRA for May = 190.3 acre-feet or about 0.083 inches off the lake. 

Water Pumped by Dallas for May = 5943 acre-feet or about 1,936,534,870 gallons.  This equals about 2.58 inches of water off the surface of the lake by pumping. 

Water Released by the SRA through the Flood Gates for May = 31,632.4 acre-feet or about 10,307,461,825 gallons.  This is the equivalent of taking 1.14 feet or about 13.7 inches of water off Lake Fork when it is full and dumping it downstream.  

So, the total water removed from the lake for May was about 22.96 inches. 

2016 Totals through May:

Evaporation for 2016 = 24.34 inches or about 56,165 acre-feet.

Rainfall Recorded by the SRA for 2016 at the SRA Headquarters = 23.34 inches. 

Water Released Downstream for Communities by the SRA for 2016 = 844.8 acre-feet or about 275,279,263 gallons.  This has totaled about 0.366 inches so far for 2016.

Water Pumped by Dallas for 2016 = 27,721.8 acre-feet of about 9,033,187,341 gallons.  This equals about 12.0 inches of water removed from the lake so far for 2016.

Water Released Downstream by the SRA through the Flood Gates when the Lake was Overfull in 2016 = 244,218 acre-feet or about 79,578,777,205 gallons.  This is the equivalent of 8.82 feet of water taken off the lake so far in 2016. 

So, the total amount of water removed from the lake so far in 2016 is about 328,950 acre-feet or about 11.88 feet.  About 74% of that water has left the lake through the flood gates when the lake was overfull to prevent damage to the dam.  

One other observation is so far Dallas Water Utilities has pumped 27,721.8 acre-feet from Lake Fork this year.  Dallas has rights to 131,000 acre-feet, so they have taken "only" 21.2% of the water they are entitled to take and we are 42% of the way through the year.  So far this year Dallas has averaged 59.4 million gallons per day of pumping from Lake Fork. 

April 2016:

 

Below are the pumping, water releases and evaporation totals for April 2016.

Evaporation for April = 6.28 inches or about 14,650 acre-feet.

Rainfall Recorded for April at the SRA Headquarters = 9.84 inches.  

1/ Water Released Downstream for Communities by the SRA for April = 184.1 acre-feet or about 0.079 inches off the lake.  

Water Pumped by Dallas for April = 5,992.9 acre-feet or about 1,952,794,855 gallons.  This equals about 2.57 inches of water off the surface of the lake by pumping. 

Water Released by the SRA through the Flood Gates for April = 82,989.4 acre-feet or about 27,042,212,175.16 gallons.  This is the equivalent of taking 2.96 feet or 35.5 inches off the surface of Lake Fork when it is full and dumping it downstream.

So, the total water removed from the lake for April was about 44.4 inches.    

 

2016 Totals through April: 

Evaporation for 2016 = 17.74 inches or about 41,393 acre-feet. 

Rainfall Recorded by the SRA for 2016 at the SRA Headquarters = 21.49 inches 

1/ Water Released Downstream for Communities by the SRA for 2016 = 654.5 acre-feet or about 213,269,741 gallons.  This has totaled about 0.28 inches off the lake so far through 2016.

Water Pumped by Dallas for 2016 = 21,778.8 acre-feet or about 7,096,652,470 gallons.  This equals about 9.3 inches of water taken off the lake so far for 2016.

 

Water Released Downstream by the SRA through the Flood Gates when the Lake was Overfull in 2016 = 212,585.6 acre-feet or about 69,271,315,379.8 gallons.  This is the equivalent of 7.6 feet of water taken off the lake so far in 2016.  

 

So, the total amount of water removed from the lake so far in 2016 is about 276,412 acre-feet or about 9.87 feet.  About 77% of that water left the lake through the flood gates when the lake was overfull to prevent damage to the dam.  
 

One other observation is so far Dallas Water Utilities has pumped 21,778.8 acre-feet from Lake Fork this year.  Dallas has rights to 131,000 acre-feet, so they have taken "only" 16.6% of the water they are entitled to take and we are 1/3 of the way through the year.  So far this year Dallas has averaged 58.5 million gallons per day of pumping. 
 

1/ - To clarify the water released to communities downstream by the SRA when you are below the dam looking at the gates you will notice 2 pipes releasing water towards the lower right side of the gates.  This is how the SRA releases water downstream to communities.  These pipes flow most of the time, but as you can see from the numbers above this is a very small amount of water released compared to evaporation, Dallas pumping or water releases through the gates.

March 2016
 

Below is the data for pumping, water releases and evaporation for March 2016.

Evaporation for March = 5.84 inches or about 13,140 acre-feet.

Rainfall Recorded for March at the SRA = 8.10 inches. 

Water Released Downstream for Communities by the SRA for March = 251.6 acre-feet or 0.11 inches off the lake.  

Water Pumped by Dallas for March = 5,864 acre-feet Or 1,910,792,609.6 gallons.  This equals about 2.61 inches taken off the lake by pumping.  

Water Released by the SRA through the Flood Gates when the Lake was Overfull from Rain for March = 90,698.2 acre-feet or 29,554,135,447.5 gallons.  This is the equivalent of taking 3.28 feet or 39.4 inches off the surface of Lake Fork when it is full and dumping it downstream.   

So, the total water removed from the lake in March was about 47.96 inches.  

2016 Totals through March: 

Evaporation for 2016 = 11.46 inches or about 26,444 acre-feet.

Rainfall Recorded by the SRA for 2016 = 11.65 inches. 

Water Released Downstream for Local Communities by the SRA for 2016 = 470.4 acre-feet or 153,280,498.6 gallons. This totals about 0.20 inches off the lake for 2016.  

Water Pumped by Dallas for 2016 = 15,785.9 acre-feet or 51,143,857,615.3 gallons.  This equals about 6.84 inches off the surface of the lake.  This equals about 12% of the 131,000 acre-feet that Dallas is entitled to pump from Lake Fork for the year.  

Water Released Downstream by the SRA through the Flood Gates when the Lake was Overfull in 2016 = 129,596.2 acre-feet or 42,229,103,204.7 gallons.  This is the equivalent of 4.68 feet of water being taken off the surface of the lake.  

So, the total amount of water removed from Lake Fork so far in 2016 is about 172,296.5 acre-feet or about 6.22 feet.  75% of that water was released through the flood gates to prevent the lake from getting too high on the gates. 

 

 

February 2016:

Below is the data for pumping, water releases and evaporation for February. 

Evaporation for February = 3.11 inches or about 6,998 acre-feet.

Rainfall Recorded at the SRA for February = 2.87 inches. 

Water Released Downstream for Communities by the SRA for February = 28.5 acre-feet or 9,286,765 gallons.  That equals only about 0.013 inches taken off the lake. 

Water Pumped by Dallas for February = 4,267.3 acre-feet or 1,390,505,679 gallons.  That equals about 1.9 inches taken off the lake.  

Water Released by the SRA through the Flood Gates when the lake was Overfull from Rain = 0.  

So, the total water removed from the lake in February was about 5 inches, but some of that was replaced by the 2.87 inches of rainfall.  I guess it is not surprising that the lake level stayed fairly constant in February.  

2016 Totals through February:

Evaporation for 2016 = 5.62 inches or about 12,645 acre-feet.

Rainfall Recorded at the SRA for 2016 = 3.55 inches. 

 

Water Released Downstream to Communities by the SRA for 2016 = 218.8 acre-feet or about 7,103,561 gallons.  This totals about 0.097 inches for 2016.

Water Pumped by Dallas for 2016 = 9,921.9 acre-feet or 3,233,065,006 gallons.  This equals about 4.41 inches removed from the lake.  This represents about 7.6% of the 131,000 acre-feet that Dallas is entitled to pump from Lake Fork for the year.  

Water Released Downstream by the SRA through the Flood Gates when the Lake was Overfull in 2016 = So far this year water was only released through the flood gates in early January and those totals were 38,898 acre-feet or 12,674,967,757 gallons.  That was the equivalent of about 1.43 feet or 17.1 inches of water off the lake.  

So, the total water removed from Lake Fork through February is about 61,688.7 acre-feet  or about 2.28 feet or 27.4 inches.  Well over half of that came from the releases through the gates in early January to prevent the lake from getting too high on the gates. 

 

January 2016:


Evaporation for January = 2.51 inches or about 5,697 acre-feet.

 

Rainfall Recorded at the SRA for January = 0.68 inches.

 

Water Released Downstream for Communities by the SRA for January = 190.3 acre-feet or 62,009,521 gallons, which is the equivalent of about 0.08 inches taken off the lake's surface. 

Water Pumped by Dallas for January = 5,654.6 acre-feet or 1,842,559,326 gallons or about 2.50 inches removed from the lake's surface.  This represents about 4.3% of the 131,000 acre-feet that Dallas is entitled to take for the year.  

Water Released Downstream by the SRA through the Flood Gates when the lake was Overfull from Rain in early January = 38,898 acre-feet or 12,674,967,757 gallons.  This is the equivalent of 1.43 feet or 17.1 inches of water off the surface of the lake that had to be dumped downstream.  

So, the total amount of water that left Lake Fork in January was 22.2 inches off the surface of the lake or 1.85 feet or about 50,440.6 acre-feet.  Dumping that water downstream this time of the year is really painful as we all know it will probably be needed in mid-summer, but of course the SRA must keep the water from getting to much above full pool.

 

 

December 2015:

 

Evaporation for December = 2.83 inches

 

Water Released Downstream for Communities by the SRA for December = 61,911,766 gallons or 190 acre-feet or about 0.007 feet taken off the lake’s surface.

 

Water Pumped by Dallas Water Utilities (DWU) for December = 8,002 acre-feet or 2,607,462,903 gallons or about 0.31 feet taken off the lake’s surface. 

 

Water Released Downstream by the SRA through the Flood Gates when the Lake was Overfull from Rain in December = 204,204 acre-feet or about 7.4 feet off the surface of the lake.  Just in December this equaled 66.5 billion gallons of water that had to be released downstream.

 

2015 Year Totals

 

Evaporation for 2015 = 75.24 inches or 6.27 feet. 

 

Water Released Downstream for Communities by the SRA for 2015 = 7,395 acre-feet or 2,409,671,103 gallons or about 0.284 feet taken off the lake’s surface for 2015.

 

Water Pumped by Dallas Water Utilities (DWU) for 2015 = 60,756.23 acre-feet or 19,797,435,000 gallons or 2.2 feet of water removed off the surface this past year by DWU. 

 

Water Released Downstream by the SRA through the Flood Gates when the Lake was Overfull from Rain for 2015 = 366,940.2 acre-feet or about 13.3 feet of water taken off the surface for 2015. 

 

So for the full year o f 2015 about 22 feet of water have been removed from the lake through evaporation, releases and pumping.  It is worth noting that DWU “only” pumped 60,756 acre-feet from Lake Fork this year or less than half of what they are entitled to pump, which is about 131,000 acre-feet. 

The total rainfall measured at the SRA headquarters rain gauge for 2015 was an amazing 74.99 inches (the normal average is about 44 inches).

 

 

November 2015:

 

Evaporation for November = 2.91 inches.

 

Water Released Downstream for Communities by the SRA for November = 267,835,082 gallons or 822 acre-feet or about 0.03 feet taken off the lake's surface.

 

Water Pumped by Dallas Water Utilities (DWU) for November = 2,787,480,000 gallons or 8,555 acre-feet or about 0.295 feet off the surface of the lake.

 

Even though evaporation slowed greatly in November it still represents by far the greatest loss of water from the lake.  I was surprised that DWU pumped 93 million gallons per day from Lake Fork for November, but the good news is they have turned the pumps off for awhile as we move into the low demand months for water.  Currently they are drawing water from Tawakoni to meet their East Operations needs.

 

Year to Date Through November:

 

Evaporation for the year through November = 72.41 inches or 6.03 feet.

  

Water Released Downstream for Communities by the SRA for the Year through November =  2,347,865,082 gallons or 7,205 acre-feet, which is about 0.249 feet off the lake's surface.

 

Water Pumped by Dallas Water Utilities (DWU) for the Year through November = 16,289,900,000 gallons or 49,992 acre-feet, which equals about 1.72 feet off the lake's surface.

 

Water Released Downstream by the SRA through the Flood Gates when the Lake was overfull from Rain through November = 162,736.2 acre-feet of about 5.6 feet taken off the lake's surface.

  

So, for the year through November about 13.6 feet of water have been removed from the lake through evaporation, releases and pumping.  Thanks to abundant lake inflows from an unbelievable year of rainfall the lake is currently above full pool.  

 

October 2015:

 

Evaporation for October = 10.45 inches, which equals about 24,113 acre-feet.  

 

Water Released Downstream for Cities by the SRA for October = 541,743,308 gallons or 1,662.6 acre feet or about 0.062 feet taken off the lake. 

 

Water Pumped by Dallas Water Utilities (DWU) for October = 262,000,000 gallons or only 804 acre-feet or about 8.4 million gallons per day.   This equals about 0.029 feet of water removed from the lake.  This was way less than the water taken during the summer months. So, again evaporation is by far the major source of water loss for Lake Fork in October..  

 

Year To Date Through October

 

Evaporation for the Year Through October = 69.5 inches or 5.79 feet or about 156,330 acre-feet..

 

Water Released Downstream by the SRA for Cities Through October = 6,363.4 acre-feet.  

 

Water Released by the SRA Through the Flood Gates when the Lake was Over Full this Spring = 94,659.5 acre-feet. 

 

DWU Water Pumped for the Year through October = 34,309.1 acre-feet.  (Note: DWU is entitled to pump 131,000 acre-feet, so they will be well under that for 2015).

 

So for the year about 291,662 acre-feet of water left the lake through evaporation, releases and pumping, which is well over 10 feet of water taken off the lake.  Thanks to inflow from storm water runoff earlier this year and the recent generous rains the lake is now currently full.  The surface area of the lake is currently at  full pool, which 27,690 surface acres.  
 

The dam is not designed for flood storage, so if the forecasts are correct that El Nino will continue to provide lots of rainfall this winter the SRA will likely not allow the lake to go much over a half foot above full pool. 

 

One last bit of information is that DWU pumped less than 1/3 of the water they could have pumped this summer.  Had DWU pumped their full allotment then there would have been another 3.5 feet of water replace.

 

September 2015

 

Evaporation for September = 8.60 inches, which equals about 17,676 acre-feet.

  

Water Released Downstream for Cities by the SRA for September = 627,658,040 gallons or 1,926.2 acre feet or about 0.078 feet taken off the lake.

 

Water Pumped by Dallas Water Utilities (DWU) for September = 2,661,540,000 gallons or 8,168 acre-feet or about 88.7 million gallons per day.   This equals about 0.33 feet or about 3.96 inches of water removed from the lake.  So, again evaporation is by far the major source of water loss for Lake Fork in September, but DWU continued to increase pumping. 

 

DWU pumped about 73 million gallons per day in August compared to the 88.7 million gallons per day pumped in September.  Year To Date Through SeptemberEvaporation for the Year Through September = 59.55 inches or 4.96 feet or about 122,338 acre-feet. 

 

Water Released Downstream by the SRA for Cities Through September = 5,204.6 acre-feet.  

 

Water Released by the SRA Through the Flood Gates when the Lake was Over Full this Spring = 94,155.5 acre-feet. 

 

DWU Water Pumped for the Year through September = 39,477 acre-feet.  (Note: DWU is entitled to pump 131,000 acre-feet, so it appears they will be well under that for 2015).

 

So for the year about 261,175 acre-feet of water left the lake through evaporation, releases and pumping, which is about 10.6 feet of water.  Thanks to inflow from storm water runoff earlier this year the lake is currently at about 2.17 feet below full pool.  The surface area of the lake is currently at 24,665 surface acres.  At full pool the lake is 27,690 surface acres.  
 

As the lake continues to recede it becomes even more important that the forecasts for above normal precipitation this winter hold true. 

 

August 2015 (Cont. from Newsletter)

 

Evaporation for the year through August = 50.95 inches or 4.24 feet or about 115,000 acre-feet.

 

 

Note:  I had someone recently try to tell me that the bulk of evaporation is caused by landowners and golf courses using water for irrigating.  This is totally false.  The SRA maintains a large concrete basin or pan of water in a fenced area.  They record the actual evaporation every day from the surface of the pan, so losses due to irrigating are totally separate from evaporation.  Some of you may recall a couple of years ago I reported on the water used for irrigating and found that the 730 or so permits issued by the SRA for irrigation only result in less than 1 inch of water

being removed from the lake each year.

 

 

Water Released Downstream by the SRA for Cities – So far, through August, the SRA has released 3,278.4 acre-feet of water downstream.  That equals only about 0.12 feet or about 1.5 inches of water off the surface of the lake. 

 

 

Water Released Downstream by the SRA through the flood gates when Lake Fork was over full – The SRA released 94,155.5 acre-feet of water downstream early this summer when the lake was over full due excessive rain and runoff.   That equals about 3.5 feet of water that had to be dumped.  As you will recall Lake Fork is not a flood control reservoir and the flood gates are not designed to be able to hold water, so the SRA tried to manage the lake to not exceed any more than 0.5 feet above full pool. 

 

 

DWU Water Pumped for the Year through August – DWU has pumped 31,309 acre-feet of water from Lake Fork through August of this year.   That equals about 1.15 feet of water or 13.8 inches of water taken off the surface due to pumping.  During August DWU really ramped up pumping from Lake Fork taking over 73 million gallons per day, which equates to 6,948 acre-feet or 2,264,048,112 gallons of water.  That sounds like a lot of water, but it actually equates to about 0.28 feet of water or 3.4 inches of water off the surface of the lake. 

 

 

Note:  DWU reported that during May and June they pumped exclusively from Lake Tawakoni to provide water for their Eastside Operations.  With their current pipe and pumping system DWU can only pump from either Tawakoni or Fork, but not both at the same time.  Ray Hubbard is the other lake they draw from for their Eastside Operations and its intake was being dredged at that time.  Starting in July DWU switched from Tawakoni to Lake Fork.  Part of the reason for the increase in pumping from Lake Fork is that the NTMWD began demanding their water right of 17 million gallons per day.   Below is a summary table showing how much water in acre-feet has been pumped from each of the DWU Eastside Operations reservoirs as of 9/18/2015.

 

As of 9/18/2015 Ray Hubbard was down 2.17 feet, Tawakoni 1.08 feet and Lake Fork 1.61 feet. 

 

 

For the year about 244,000 acre-feet of water has left Lake Fork through evaporation, releases and pumping, which is about 9 feet of water.  Thanks to all the inflow from storm runoff early this summer the lake is currently only about 1.7 feet below full pool.  The surface area of the lake is currently about 25,175 surface acres.  At full pool the lake is 27,690 surface acres.

August 2015

 

Evaporation for August = 11.2 inches, which equals about 24,000 acre-feet or about 0.93 feet.

Water Released Downstream for Cities by the SRA for August = 1,455.7 acre-feet, which equals 474,341,883 gallons or about 0.057 feet. Water Pumped by Dallas Water Utilities (DWU) for August =  6,948.1 acre-feet or 2,264,048,112 gallons for the month or about 73,033,810 million gallons per day on average.  This equals about 0.28 feet of water or about 3.4 inches of water for the month.  So, evaporation was by far the major source of the lake dropping in August, but I was surprised to learn that DWU pumped as much as they did.  DWU pumped about 3 times what they pumped for July.    

The bottom line is the lake lost about 15 inches in August with 75% of that coming from evaporation. 

 

Year to Date Through August

 

Evaporation for the Year Through August = 50.95 inches or 4.24 feet or about 115,000 acre-feet.

 

Water Released Downstream by the SRA for Cities = 3,278.4 acre-feet.

 

Water Released by the SRA Through the Flood Gates when the Lake was over Full = 94,155.5 acre-feet.

 

DWU Water Pumped for the Year Through August = 31,309 acre-feet. 

 

So for the year about 244,000 acre-feet of water has left the lake through evaporation, releases and pumping, which is about 9 feet of water.  Thanks to all the inflow from storm runoff earlier this year the lake is currently only 1.4 feet below full pool.  The surface area of the lake is currently at 25,196 surface acres.  At full pool Lake Fork is 27,690 surface acres. 

 

Let's hope for that above average precipitation that is predicted for this winter.

July 2015

 

Evaporation for July = 11.22 inches, which equals 26,000 acre-feet or 8,472,136,400 gallons or about 0.93 feet. 
 

Water Released Downstream by the SRA for July = 528.4 acre-feet, which equals 172,143,000 gallons or about 0.02 feet. 

Water Pumped by DWU for July = 2,259.1 acre-feet or 736,126,000 gallons for the month or about 23.75 million gallons per day on average.  This equals about 0.08 feet of water or about 1 inch for the month.  

So, evaporation was by far the major source of the lake dropping in July, but I was surprised to learn that DWU pumped as much as they did.  I figured they would pump a couple of days just to run the pumps, but a couple of days should only equal about 180,000,000 gallons.  

The bottom line is the lake receded by just about 1 foot in July with over 90% of that due to evaporation.

June 2015

 

What a difference a couple of months makes.  Dallas Water Utilities (DWU) did not pump any water from Lake Fork during the month of May.   DWU is in the process of dredging the Ray Hubbard pump station intake, which will continue through June.  They are currently only pumping water from Lake Tawakoni to feed the Eastside Operations plus they are also moving some water from the west side lakes since they are so much above full pool.   DWU is not currently taking water from Lake Fork to meet the commitment to NTMWD.  NTMWD's lakes are all full, so they do not need the Lake Fork water at this time.  

 

The SRA released nearly 72,000 acre-feet of water through the gates once the lake was full.  Had they not released the water then Lake Fork probably would have been well over 2 feet above full pool.  For those us with boat houses on the lake we are glad they released the water.  In addition 252 acre-feet were released for commitments to downstream communities.  Quitman and Bright Star-Salem took 28 acre-feet through their intakes. 

 

At this time Lake Fork remains at 0.4 of a foot above full pool.  The lake is beautiful.

May 2015

 

A few weeks ago Ken Delnegro at Dallas Water Utilities informed me there is planned construction work on the Iron Bridge Pump Station at Lake Tawakoni that would likely require DWU to hold the water level down at Tawakoni.  So, I emailed Ken this week to see if that is why Tawakoni has not reached full pool.  

 

Ken informed me that Tawakoni is down due to lack of rain in its watershed and not the result of pumping.  He reminded me that Tawakoni is a huge lake and the last 3 feet is a lot of water. 

 

As part of his response Ken informed me that about 3 weeks ago they switched from pumping at Lake Fork to Lake Tawakoni.   They will be dredging the Lake Ray Hubbard pump station intake through June and didn’t want to be on Lake Fork-only water due to treatability issues, so they are on Tawakoni-only through June.

 

Ken also shared that he does not know when the Iron Bridge Pump Station work will occur, but it will be anytime soon.

 

Dallas's Eastside Operations is "only" using 80 million gallons per day  from Tawakoni due to rain-related low demand across the system.  He said that since their western lakes (Grapevine, Ray Roberts and Lewisville) are 5-9 feet above conservation pool, they will favor those until they reach normal pool.  He suspects that will take until midsummer at least. 

 

I specifically asked Ken if they had the ability to move water from their Westside Operations to their Eastside Operations thinking that would make sense since the western lakes have excess water.   He said they can move water throughout their distribution system but they cannot operate very long without the Eastside Operations. 

 

My take away from this is that right now it appears there will be very limited pumping from Lake Fork until at least mid-summer.   I will continue to provide the monthly pumping reports to see if this is the case.

March 2015

 

Dallas Water Utilities pumped 1,672,420,000 gallons of water from Lake Fork Reservoir for the month of March.  That is equal to 5,132.5 acre-feet of water and 53.9 million gallons per day.  This was more than what was pumped in February, which was 1.4 billion gallons/3,872 acre-feet/45 million gallons per day, but still far less that what they pumped last fall. 

 

So far for the year they have pumped 16,132.5 acre-feet, which equals about 12.3% of the total that DWU is entitled to pump for the entire year of 2015.  The water pumped by DWU for the month of March equals about 2.5 inches of water off the surface of the lake. 

 

Those of you who attended the Lake Fork Sportsman's Association meeting in Emory over a year ago will recall that DWU reported they had signed a contract to deliver 17.8 million gallons per day of water to Lake Tawakoni for use by the North Texas Municipal Water District.  Early in March DWU initiated delivery of that water.  It is included above in what was pumped for March.

February 2015

 

I just received the pumping report for February.  DWU pumped nearly 1.4 billion  gallons for the month or 45 million gallons per day for February.  That is significantly less than the 100 million gallons per day they were pumping last Fall.  The water pumped for February equals 3,872 acre-feet.  So far DWU has pumped 11,000 acre-feet of water since January 1, which represents 8.4% of the 131,000 acre-feet that DWU is allowed to take each year.  The water pumped for February equals about 2.2 inches of water removed off the lake's surface.
 

The SRA reported 4.15 inches of rainfall for the month of February.  That moisture plus the lower pumping by DWU has allowed the lake to rise from 7.09 feet low to 6.18 feet low during February.  
 

The ground is saturated and the ponds are all full, so any intense storms right now would likely create the kind of runoff that we need to make headway in refilling the lake.

January 2015

 

I just received the pumping for January.  DWU pumped 2,322,780,000 gallons or 75 million gallons per day for January.  From August through December DWU had averaged pumping over 100 million gallons per day.  You will recall that DWU reported that they planned to take less water in January due to some repairs they were making in the system, so it appears that is what happened.  The water pumped for January equals 7,128 acre-feet.  Since DWU is allowed to take up to 131,000 acre-feet per year then that means they pumped 5.4% of the total allowed for the year in January.  The water pumped for January equals about 4 inches of water removed off the lake's surface.
 

This seems like a good news/bad news kind of thing.  It is good to know that with the rainfall we received in January that the lake held its own despite 75 million gallons per day being pumped.  The bad news is that we did not gain much for the rainfall received and most likely DWU will eventually get back to pumping over 100 million gallons per day.  

As usual we need to hope and pray for more intensive rain events this spring.
