Montour County
May 9-13, 2005

Lake Chillisquaque is a 165-acre impoundment on the Middle Branch Chillisquaque Creek located 11 miles north of Danville, Montour County. The lake is contained within the Montour Preserve, which is owned by Pennsylvania Power and Light (PPL). The reservoir serves as a source of cooling water for the PPL Montour Steam Electric Station and is open to public angling and boating. In addition to containing Lake Chillisquaque, a state-of-the-art environmental education center is also located at Montour Preserve. PPL maintains one boat launch and boating is restricted to non-powered boats and those propelled by electric motors only.

Lake Chillisquaque is one of 18 lakes throughout the state that are currently managed with Panfish Enhancement Special Regulations. These regulations are intended to increase the number, quality, and size of panfish through the use of minimum length limits on sunfish species (bluegills and pumpkinseeds) and crappies (black and white). Under these regulations, minimum length limits of 7 inches were established for sunfish and 9 inches for crappies. The combined creel limit is 20 for each species with the total number creeled not to exceed 50 panfish combined. Commonwealth Inland Waters Regulations for seasons, sizes, and creel limits are currently in effect for all other species and all fish populations are maintained through natural reproduction. The panfish catches will be used to assess the effect of the Panfish Enhancement Special Regulations and the final evaluation will be made after another trap net survey in 2007.
