A lake with no outlet has a steady state volume of 5 x 1011 m3, the salt concentration in the lake is 100 g/L. The input to the lake is 3 x 109 m3/year with a salt concentration of 0.2 g/L. Assume that rainfall is negligible. At some point in the past the outlet to this lake stopped flowing and the input was balanced by evaporation, resulting in an steady increase in salt concentration. Estimate how long ago the outlet to the lake stopped flowing and state assumptions
