Fish consumption advice (2026 list)
No lake-specific rows for Butler County lakes 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.”
“Fish stocked from PFBC state fish hatcheries are subject to the blanket one-meal-per-week consumption advisory that applies to recreationally caught sport fish in Pennsylvania.”
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.”
