The Department of Environmental Protection is investigating at a lake in Delaware County after dozens of fish were found dead.
Nearly 80 fish were discovered this afternoon, floating at the top of the Ridley Park lake at Constitution Avenue and Dupont Street.
"We know very little at this point, we have the D.E.P coming out to conduct some follow-up tests. We've already done some initial testing of the water, no obvious contaminants have been found in the water," said Borough Manager Dawn Human.
Residents are being asked not to fish or go into the lake until authorities finish testing the water.
Human says it's possible the dead fish may have washed up in this week's storms.
