A lake had a water surface elevation of 110.00m above datum at the beginning of a certain month. In that month, the lake received an average flow of 66.0m3 /s from surface runoff sources. In the same period the outflow from the lake had an average value of 66.5m3 /s. Further, in that month, the lake received a rainfall of 150mm and the evaporation from the lake surface was estimated as 7.40cm. Write the water budget equation for the lake and calculate the water surface elevation of the lake at the end of the month. The average lake surface area can be taken as 5000ha. Assume that there is no contribution to or from the ground water storage

Question
A lake had a water surface elevation of 110.00m above datum at the beginning of a certain month.
In that month, the lake received an average flow of 66.0m3
/s from surface runoff sources. In the
same period the outflow from the lake had an average value of 66.5m3
/s. Further, in that month, the
lake received a rainfall of 150mm and the evaporation from the lake surface was estimated as
7.40cm. Write the water budget equation for the lake and calculate the water surface elevation of
the lake at the end of the month. The average lake surface area can be taken as 5000ha. Assume
that there is no contribution to or from the ground water storage
