Beaver Creek Dam
Chester County, Pennsylvania
History
Originally constructed in 1976 as part of the Brandywine Watershed Plan, the Beaver Creek Dam provides flood reduction for communities that border the Beaver Creek, East Branch Brandywine Creek and the main tributary of the Brandywine Creek. NRCS is providing technical support and financial assistance to Chester County Water Resources Authority (CCWRA) to extend the life of the dam and rehabilitate the dam to meet state and federal safety standards. Once work is completed, the Beaver Creek Flood Control Dam will continue to provide flood control functions, enhance wildlife habitat and improve water quality in Beaver Creek.
