Chambers Lake at Hibernia County Park
About the Lake
Chambers Lake
Chambers Lake is a 90-acre water supply reservoir and regional flood control facility of the Chester County Water Resources Authority.

In 1994, the lake was formed by the construction of Hibernia Dam on Birch Run to provide a supplemental source of local drinking water, and needed flood control for the Brandywine Creek watershed. The lake also offers excellent recreational opportunities, especially fishing, boating, hiking and bird watching.

In September 1996, the lake was officially dedicated Chambers Lake, in memory of J. Franklin Chambers, the first superintendent of Hibernia County Park.

Fishing & Boating

Fishing is permitted 24 hours a day. The lake is stocked with warm water species, including Panfish, Channel Catfish, Chain Pickerel, and Smallmouth and Largemouth Bass. Chambers is one of only three Pennsylvania lakes that is a Panfish Enhancement Area, which regulates number, quality and size of panfish through minimum length limits. It is also one of a select few in the Big Bass Program. Therefore, the lake is closed to bass fishing from late April to early June.

A public fishing pier is open on the lake’s north side and may be accessed from the Lake Trail. Other shoreline fishing is permitted, but is prohibited from the dam breast itself. There is a public parking lot and boat ramp off Wagontown Road. After park hours, parking is permitted for fishing only.

A separate brochure, Fishing Opportunities, provides details about fishing resources within Chester County parks.

No gasoline powered boats or engines are permitted to be operated on the lake; only electric-powered or self-propelled boats are allowed. All watercraft must be registered with the Pennsylvania Fish and Boat Commission. Swimming and sailing are prohibited.
