PFBC biologist report
Gear: trap nets, hoop nets, night electrofishing
Trap nets captured 720 Black Crappies measuring 3 to 14 inches. (p. 2)
Trap nets captured 1,145 White Crappies measuring 3 to 12 inches. (p. 2)
Catch rates for Largemouth Bass over 12 inches and over 15 inches were 44 and 20 fish per hour, respectively. (p. 3)
The hoop nets captured 3 Channel Catfish measuring 15 to 26 inches. (p. 3)
PFBC's plan, in our words: PFBC will evaluate growth and other data to consider management options that increase the abundance of larger panfish. (p. 2)
Historical survey — more than 10 years old; fish populations change.
Gear: trap nets, night electrofishing
Trap nets captured 1,276 Black Crappie measuring 4 to 18 inches. (p. 2)
The 3,203 White Crappie ranged from 3 to 16 inches. (p. 2)
The Largemouth Bass catch rate was 79.5 fish per hour. (p. 4)
PFBC's plan, in our words: PFBC will analyze crappie and bass growth to decide whether Big Bass regulations could increase bass density and predation on crappie. (p. 4)
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.

Fish consumption advice (2026 list)
No lake-specific advice for Lake Oneida in the 2026 list.
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.”
The 2026 advisory has no lake-specific row for Lake Oneida. The statewide advice — no more than one meal (1/2 pound) a week of sport fish — still applies. Not medical advice.
