Rarely and I mean rarely do I eat fish from the lake and never from below the dam at Shenango. Reason is when Steel car was running they dumped tons of toxins in the river. Go downstream to Transfer and you had Greenville metals that had a radioactive sight right along the river. Add Damascus tube with their chemicals then add greenvile tube dumping. It adds to what is a very polluted river. This all settled in the lake.
Floated the river 2 yrs. ago in July and saw an eruption or massive boil of a black tarry mass that burped to the top in front of me. This boil was the size of a 2 stall garage. This was at a deep hole where the rr tracks cross the river below Greenville.
Pymy had problems with waste being dumped in from sewage systems along with ag chemicals. Still I do eat the fish from there. Very few places to eat fish in Pa. that are not contaminated some way or another. Them natives from clean mt. streams are tasty but take way too long to replenish the population...so eat sparingly accourding to the pfc recommendation.
