Below are the pumping, water releases and evaporation for 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.
