During the month of june, a lake having surface area of 200 acres has an inflow of 15 cfs, and outflow of 12 cfs, and a total seepage loss of 1 in. the water level at the beginning and end of the month was measured as 200 ft and 200.75 ft respectively. if precipitation during the month was 2 in, estimate evaporation losses from the lake (in inches). assume that changes in the surface area with water level are insignificant.
