Highest pool level surface acres 40,500
Miles of shoreline at high pool level 343
Low (conservation) pool level surface acres 31,500
Miles of shoreline at low pool level 276
CWS avg. water usage per day 7.3 million gal
*Lake level effect in one year 2”
Normal evaporation rate 95 to 125 million gal.
*Lake level effect in one year 43”
Daily amount of water released through the dam. 25 mil to 4.5 bil gal.
*Measurements are based on constant lake level. In other words, no water would be added or lost from the lake over a one year period other than the amounts extracted by CWS or lost to evaporation.
