What PFBC biologists found
Apr 2022 survey · 4 years ago
PFBC biologist report
Gear: trap nets, night electrofishing, boat electrofishing
Yellow Perch were the most abundant trap net catch, with 280 individuals. (p. 1)
Black Crappie at least 8 inches long represented 68% of their trap net catch. (p. 1)
The Muskellunge trap net catch rate was 0.004 fish/h, below the management criterion of 0.01 fish/h. (p. 8)
PFBC's plan, in our words: PFBC will discontinue maintenance stockings of Muskellunge because trap net catch rates did not meet the management criterion. (p. 8)
Gear: trap nets, night electrofishing, boat electrofishing
Trap nets captured 163 Black Crappie. (p. 2)
Trap nets captured 234 Bluegill. (p. 2)
Night electrofishing captured 44 Smallmouth Bass at 15.3 fish/hr. in 2021. (p. 6)
Night electrofishing captured 37 Largemouth Bass at 12.4 fish/hr. in 2021. (p. 6)
The Muskellunge trap-net catch rate of 0.007 fish/hr. was below the management criterion of 0.01 fish/hr. (p. 7)
PFBC's plan, in our words: PFBC considers regulation changes premature without quantified angler use and expectations and a clearer understanding of the lake’s capacity to produce larger fish. (p. 8)
Findings are our short summaries of one survey at one time. Every number was checked against the cited page of PFBC's report. We don't rate lakes.

Statewide advice:“Pennsylvania has issued a general, statewide health advisory for recreationally caught sport fish: eat no more than one meal (1/2 pound) per week of sport fish caught in the state’s waterways.”
“People who regularly eat sport fish, women of childbearing age and children are particularly susceptible to contaminants that build up over time.”
DEP: “The advisory listing was current at the time this summary went to press. Fish consumption advisories may have been issued or lifted since that time.”
PFBC's special-regulation data (Mar 2026) lists this lake under Brood Stock Lakes Program, but the 2026 Summary's Brood Stock Lakes Program list (p. 15) does not name it. Check the posted signs and PFBC.
