<P> The water table may vary due to seasonal changes such as precipitation and evapotranspiration . In undeveloped regions with permeable soils that receive sufficient amounts of precipitation , the water table typically slopes toward rivers that act to drain the groundwater away and release the pressure in the aquifer . Springs , rivers , lakes and oases occur when the water table reaches the surface . Springs commonly form on hillsides , where the Earth 's slanting surface may `` intersect '' with the water table . Groundwater entering rivers and lakes accounts for the base - flow water levels in water bodies . </P>
