The inflow for the month of April is 3.26 cubic meter per second, and the outflow is 2.93 cubic meter per second. The total

monthly precipitation is 15.2 cm and the evaporation is 10.2 cm. The seepage is

estimated to be 2.5 cm. Estimate the change is storage during the month of April.

**drwls**, Tuesday, February 22, 2011 at 2:25amConvert evaporation, rainfall and seepage to cubic meters by multiplying the appropriate level changes (in meters) by the lake area (in square meters)

Then use

Storage level change =

(Inflow) - (outflow) + (precipation) - (seepage) -(evaporation)
