Hibernia Dam Regional Flood Control Facility and Chambers Lake Reservoir are located at Hibernia County Park in West Caln Township, Chester County. The dam was built in 1994 by the Chester County Water Resources Authority and USDA Soil Conservation Service, now the Natural Resources Conservation Service (NRCS). Hibernia Dam is owned and operated by the Authority and provides recreation, water supply, and flood protection for residents in Chester County.
With technical support and funding from NRCS, CCWRA completed a rehabilitation project on Hibernia Dam in the summer of 2020 in order to meet modern dam safety standards and to extend the lifespan for another 50 years. Funding for the project was provided by the County of Chester, the USDA Natural Resources Conservation Service, and Pennsylvania American Water Co. The lead construction contractor for the project was KC Construction of Ivyland, PA, and the engineering design firm was Gannett Fleming, Camp Hill, PA.
