U.S. Department of Agriculture Agricultural Research Service Mahantango Creek Watershed, Pennsylvania, United States: Long-term stream discharge database: DATA AND ANALYSIS NOTE

A long‐term precipitation database has been developed by the U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS) Pasture Systems and Watershed Management Research Unit to support intensive hydrologic and water quality research within WE‐38, a 7.3 km 2 experimental subwatershed of Mahantango Creek Watershed located in east central Pennsylvania and draining to the Susquehanna River. Daily precipitation data were collected at three sites, with record lengths of 40 years (1968–2007) at two sites and of 29 years (1979–2007) at a third site. Data are available on the USDA ARS's Sustaining the Earth's Watersheds—Agricultural Research Data System (STEWARDS) Web site.
