When a lake fills past its overflow depth, the water will flow into another lake or into a river and out of the system. Your program will read in the daily rainfall and display the level of each of the three lakes. For simplicity, we will assume that the lakes are cylindrical. That is, the surface area of the lake does not change with the water level. We will also assume that when it rains, the same amount of rain falls on all lakes and watersheds.
Rain increases the depth of the lakes.
Rain that falls directly into the lake adds to the depth as does water that flows into the lake from streams in the lake s watershed. While all of the water that falls directly into the lake increases the lake depth, only some of the water that falls on the ground in the watershed will flow into the lake. The ground will absorb the first 2 millimeters of any rainfall in a day. The city uses 12 million liters of water from Crystal Lake every day. Water evaporates from all of the lakes lowering the lake levels an average of 1.0 millimeter per day.
