I wish we had more pickerel in SE Pa from the standpoint of ice fishing, but we do not have many in SE streams, rivers, or public lakes. Fishable populations exist in about 10 or so public lakes plus parts of the upper Schuylkill River. Eliminate Schuylkill Co and you are down to a few public lakes of which I am aware that have reasonable populations.......Lake Towhee, possibly Lake Warren, Leaser Lake, possibly Chambers Lake, Hopewell Dam, possibly Scotts Run Lake. Nockamixon's population has greatly diminished such that they are not worth targeting, at least not on their own. They were extirpated from Struble Lake decades ago. There is CP reproduction in the Schuylkill River in the Hamburg-Bern vicinity. Someone introduced CP to Speedwell Forge Lake, so it may be that another lake will eventually be added to my list. The canals also have some.
