6. Runoff from a 200 mile² catchment drains into a reservoir than has an average surface area of 4000 acres. The reservoir is to be used for municipal water supply. Annual rainfall over the watershed is 40 inches and the annual runoff is 2 inches. Evaporation from the reservoir averages 40 inches per year. If the surface area of the reservoir is roughly constant with depth, how much will the reservoir depth change in one year?
