Experimental Watersheds and Gauging Stations

Andrews Forest (Lookout Creek) Experimental Watersheds

There are nine small experimental watersheds and ten gauging stations on the Andrews Forest, including the station near the mouth of Lookout Creek.  All gauging stations record stream flow, water conductivity, and water and above-stream air temperature continuously.  Most stations also collect water samples proportional to steam flow, which are composited at three-week intervals for chemical analysis.  Stream chemistry data from the Andrews Forest and other small watershed studies across the U.S. have been organized into a stream chemistry database for broader scale studies.  At five of the small watersheds an annual survey of sediment basins provides data on bedload accumulation. The experimental watersheds have also been sampled for vegetation, soils and other data needed to understand hydrological and ecological processes.
