This is a sad loss to our fishing community. Big Mike was a great guy whole loved fishing and would talk fishing with anyone. My heart goes out to the Burt family.
I found that 21" on 10 spin Dr works the best. It gives the fly a little more attractive look. Buy I also run my cut bait heads at 32" on big weenie 10 and 13 flashers. To me shorter lead lengths work the best
Catherine creek actually stop at a bridge in Montour campgrounds. From there to the 414 bridge is considered the canal. The creek starts at the marsh in horseheads by the domes.
Seneca lake is the easiest lake to fish. It took me 3 yes to figure it out. I know where to go at what season to catch fish. I give pointers out even helped couple guys catch winning derby fish. You just need to put time on the lake.
