The Lakes Shrink A Toshka Project, Egypt story
Water
The only two places for water in this arid region to go are into the air or into the ground. The underlying limestone prevents much ground infiltration. In the Toshka region, annual precipitation averages a meager 1.5 millimeters, and the potential evaporation rate is 14–15 millimeters per day. With no natural outlet and reduced water input to these lakes from Lake Nasser, the water evaporated quickly.
