Don't know if it's still true, because I haven't fished much since my late teen years, but when I was a kid the best muskellunge (musky) fishing in PA was supposed to be where the Schuylkill meets the Perkiomen. I've been there a number of times, but not recently, and I never caught a musky ; -). I think I know exactly where you are standing. Doesn't look like it has changed much on the far banks...
