I discovered this stream by accident one day, probably more than 15 years ago now, before wild trout streams like this were posted on the internet by the state of PA. I was all set to fish the mainstem of Slippery Rock one day with light spinning gear, but when I got to the stream I found that it had apparently muddied up overnight due to a local thunderstorm. As I worked my way up from the bridge I spotted this little tributary. On a hunch, I worked upstream from the mouth and quickly determined that there were fish in there. I had two follows in the first hole casting a small spinner. I only ended up catching one fish on that trip, but after that I always went back with my 7' for 3/4 wt.
I caught at least 2 browns in that stream that were over 17" as well as one that was 15". Many of the fish that I caught at that time were in the 8-12" range which is not too shabby for a stream that size. The fish were generally very spooky due to the small size of the stream and the clear water, but catching them on any well presented fly was generally not a problem.
All of the fish that I caught there were beautiful wild browns. The water was always cold, even on the hottest summer days. I never saw a whole lot of insect activity except for some yellow and green stone flies. I'm sure that there are probably caddis as well as a few mayflies, but basic attractor dries such as Wulff patterns always worked well for me. The best thing for me was that I never saw another fisherman there. I did see a few hikers and even a couple of folks on horseback, but never another angler.
I haven't fished it for at least 11 years now and have no idea what the current condition of the stream is. The last couple of times I fished there some sunfish had somehow got into the stream which I took to be a bad sign. Perhaps it was from an upstream farm pond that flooded. If there is going to gas well drilling nearby that cannot be good. I hope the drilling does not pollute this beautiful stream. I never kept a trout out of this stream and only ever used barbless hooks. What a gem!
