A lake with a surface area of 1260 acres was monitored over a period of time. During a one-month period, the inflow was 44 cfs, the outflow was 26 cfs, and a 1.6 in. seepage loss was measured. During the same month, the total precipitation was 5.2 in. Evaporation loss was estimated as 3 in. Estimate the storage change (ac-ft) for this lake during the month. Note: 1 ac is equal to 43560 ft²

Please help.

Example Problem Water budget for a lake provides following observations: Precipitation, P = = 43 in./yr. Evaporation, E = 53 in./yr. Inflow to Lake, Qin = 1 in./yr. Outflow from Lake, Qout = 173 in./yr. Change in Lake storage, AS = -2 in./yr. Find the net groundwater flow. Solution: E SWIn GWin PPT Evap SW Out GWout

A lake with an area of 5 km2 has a net decrease in storage of 6 ha-mm. The inflowing stream rate is 2 m3/s while the outflow rate is 2.5 m³/s. If no rain fell during the month, what is the estimated total evaporation for the month? 2. (0.5. 36oor,24
