To serve our current customer group, Community Water System draws an average of 3-1/2 million gallons of water per day from Greers Ferry Lake through an intake line located just north of our treatment facility in Greers Ferry, Arkansas. Considering the vast amount of water contained in this lake, the daily usage by CWS has little or no effect on the lake. As a comparison.. the normal lake evaporation rate is between 95 and 125 million gallons of water per day, and the daily release of water through the dam can range from 25 million gallons to 4.5 billion gallons. As you can see the amount of water taken by Community Water System would in no way prove harmful to our beautiiful Greers Ferry Lake.
