Watershed

An area experiences a long period of drought forcing towns to pump out almost all of the water held in aquifers. What is the most likely result of this over pumping?

• Stability of underground rock layers will be weakened.

• Excessive growth of plants will occur in local lakes.

• Rainfall levels will increase and fill the aquifer.

• A dead zone will be created in the watershed.
