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 such as fishing, boating, hiking and bird watching.
In September 1996, the lake was officially dedicated as Chambers Lake, in memory of J. Franklin Chambers, the first superintendent of Hibernia 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. 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 can 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 located off Wagontown Road. After park hours, parking is permitted for fishing only.
Life jackets are required while underway or at anchor on boats less than 16' in length or any canoe or kayak. Visit the Fish and Boat Commission website for more information.
No gasoline powered boats or engines are permitted on the lake; only electric-powered or self-propelled boats are permitted. All watercraft must be registered with the Pennsylvania Fish and Boat Commission.
Swimming and sailing are prohibited.
