Hibernia Dam Rehabilitation Project

The Chester County Water Resources Authority (CCWRA) has requested and is receiving assistance from the U.S. Department of Agriculture, Natural Resources Conservation Service (NRCS) for Hibernia Dam and Chambers Lake Reservoir through the National Dams Rehabilitation Program.

Hibernia Dam and Chambers Lake Reservoir are located in West Caln Township and provide flood protection for 14 municipalities located throughout the lower West Branch and mainstem Brandywine Creek corridor, and provide water supplies for the greater Coatesville regional public water supply system. The dam and reservoir were constructed by NRCS in partnership with the Chester County Board of Commissioners, CCWRA, the City of Coatesville Authority (now Pennsylvania American Water Co.), and other state and local partners, and are now owned and operated by CCWRA.

Hibernia Dam was completed in 1994 to address flood control, water supply and recreation needs. It is currently serving those purposes in a safe and reliable manner. The dam was designed and constructed to meet the dam safety engineering standards in place at that time. Since then, advances in dam safety engineering have resulted in new design standards that are above and beyond those used for Hibernia Dam. The purpose of the Rehabilitation Project is to construct improvements to meet current dam safety standards. In addition, the Rehabilitation Project is evaluating other aspects of the dam that could improve the dam and extend its service life. This Rehabilitation Project began in November 2011 and is currently in the Design Phase.
