Answer:Surface water seeps into the ground and recharges the underlying aquifer—groundwater discharges to the surface and supplies the stream with baseflow.
Explanation:
What are some effects of groundwater depletion? Pumping has removed water from storage in basalt aquifers and caused declines in many areas of the Columbia Plateau. The most severe consequence of excessive groundwater pumping is that the water table, below which the ground is saturated with water, can be lowered.
