# Stream stage and water table elevation in hyporheic and ground water from McRae Ck well network, Andrews Experimental Forest, 1989-1993 ## Dataset - **Database Code:** HF010 - **Title:** Stream stage and water table elevation in hyporheic and ground water from McRae Ck well network, Andrews Experimental Forest, 1989-1993 - **Abstract:** Measurements of stream stage of McRae Ck and water table heights from a network of shallow wells located adjacent to the stream. Data were collected from September 1989 to September 1992 on an irregular basis to sample both baseflow periods and storm events across seasons of the year. Stage height was read from staff plates permanently located at several location in the mainstem channel and in a small back channel; water table elevations were measured with a weighted measuring tape with a visible signal when the tape touched the water in the well. - **Keywords:** hydrology; storms; disturbance; physical processes; hydrologic processes; streamflow; modeling; inorganic nutrients; groundwater; hyporheic zone; forests; aquatic ecosystems; streams; peak flows; low flows; disturbance; inorganic nutrients - **Temporal coverage:** 1989-09-14 to 1993-03-25 - **Principal Investigator:** Steven M.
