What land use would be the best choice for watershed drainage?

• mall

• wetland

• recreational area

A water table well and another well going into an aquifer are shown in the diagram. During a drought, the water table dries while the aquifer remains nearly full. Which best explains this?

• During the drought, the water table increases, but the water level in the confined aquifer increases.

• During the drought, the water table falls, but the confined aquifer is mostly isolated from the drought conditions and remains unaffected.

• During the drought, the water table remains constant, but the confined aquifer keeps its water level because of other sources of water.
