The lake isn't all that big....If you live 5 minutes from it, you should certainly be fishing it more often. Enough said.
Don't expect any big numbers from any PA lakes...When I put more time in with muskies, years past, PA was always good for 30 to 40 fish a season and that was putting a lot of time into it. I spent most of my time at Arthur and the most I got from it one year was 29. Not because it was better, but because its 15 mins from my house and thats where I spent most of my time. If you don't have confidence in a lake, its probably because you haven't put enough time into it and finding out what the best techniques are to use there. Time is the key, not necessarily the place except for maybe a couple of bodies of PA waters which are a cut above. Most know which they are.
I have put enough time in Western PA lakes that each has its own characteristics and I find myself using different tactics/lures/structures, etc at any given PA lake....It took me 20+ years of muskie fishing to get to this point.
