In a given month, a lake of constant surface area 1,000,000 m2 has a mean inflow of 0.40 m3/s, an outflow of 0.34 m3/s and an increase in storage of 20,000 m3. A rain gauge aside the lake measured a total rainfall depth of 30 mm for this month. If we assume that other losses from the lake are insignificant, estimate the monthly evaporation of the lake.

In a given month, a lake of constant surface area 1,000,000 m2 has a mean inflow of 0.40 m3/s, an
outflow of 0.34 m3/s and an increase in storage of 20,000 m3. A rain gauge aside the lake measured
a total rainfall depth of 30 mm for this month. If we assume that other losses from the lake are
insignificant, estimate the monthly evaporation of the lake.
