Glade Run Lake
Butler County
Spring 2010
Night Electrofishing Survey

Glade Run Lake is a 52-acre Pennsylvania Fish and Boat Commission owned impoundment located in southern Butler County off of Route 228. This lake is open to public boating (electric motors or un-powered only) and fishing. The lake is managed under the Big Bass Program.

Area 1 fisheries management personnel, along with local WCO Mike Walsh, conducted a night electrofishing survey of Glade Run Lake on May 20, 2010 to assess the largemouth bass population. A total of 204 largemouth bass were netted during 77 minutes of electrofishing. The bass ranged from 3 to 20 inches, with the majority measuring 10 to 12 inches (Figure 1). Catch per unit effort (CPUE) was excellent overall, with 160 largemouth bass being sampled per hour. However, fewer large fish (≥ 12”) were present compared with previous years (Figure 2).

Glade Run Lake is a great place to target largemouth bass, and several quality sized fish are present. It was apparent throughout the survey that plenty of stocked trout were still available to anglers.
