Depletion of Surface Water

Groundwater interacts with surface water by supplying streamflow and maintaining wetlands in times of low precipitation. On average about 40 percent of the river flow nationwide depends on groundwater (Phillips, 2001). Over-pumping of aquifers can lead to lowered stream and lake levels, and to dessication of wetlands. These impacts will be further explored in the surface water depletion section.
