I've not fished the J in a while, but if you where in the vicinity of Spruce Creek some rainbows are likely. There are wild bows in spruce and I have been told that Spring Ridge still stocks the J in that vicinity. This is now a Class A and it is illegal to stock; however, Spring Ridge continues to do so. Those who fish the J should be aware and report illegal stocking to the PFBC. I know that many like to catch wild rainbows, but we should not want the J to support such a fishery...its got a great brown tout fishery now! Good wild bow populations are isolated to true limestoners in PA like Bid Spring or Falling Spring. The temperatures in the J get too high in the support anything other than a transient fishery from spruce creek or illegal stocking. Also, keep in mind that that rainbows, either stockie or wild, would compete for limited resources with the robust wild brown trout population in the J, and ultimately knock them back a bit. My point is that it is great wild brown brown trout fishery, so why mess with it?
