Changing Stream Conditions â¢Streams can be âgaining streamsâ along one portion of their length and âlosing streamsâ along another portion, depending upon their relationship to the water table at those points. The beds of many streams are covered by silt and have a low permeability.A rainfall event, flood condition, or man-made discharge can cause the surface of a stream to rise above the elevation of the water table and force water in the stream into the groundwater system.â¢An active water supply well can locally lower the water table and attract the stream water into the groundwater system.
