Water table: upper limit of water in saturated soil. Water goes into the ground as far as an impervious layer of rock then begins flowing downhill along that rock layer to the nearest body of water such as a stream or lake. After a heavy rain or snow melt, the top surface of this ground water may be above the ground level in depressions and other areas.
