I been fishing Tionesta lake for 12 years. It has changed drastically over this time. Ever since the big floods years ago it went downhill. I use to troll the bridge to the no wake bouys with great success. It was 10 to 12' deep then with structure. Now it is 5 to 6' deep with no fish. The weeds below the stump field never came back. There use to be 20 or so stumps with 8 to 10' of water. Now there is one big stump in 2' of water. Now you have to troll the main lake with the ski boats. My numbers went down over the years. I use to have a great pattern that never let me down. Not no more. I did get my biggest fish last Memorial day trolling deep. It was 51.5"s and weighed 36 1/2lbs. I just fished it for 7 hrs on saturday with no action. I know for a fact that the locals keep any legal ski that they catch. This is one of the toughest lakes in Pa to fish. It is just nice that the lake is 6 miles from camp. This weekend I am driving over to Chautauqua. I can be there in about a hour from Tionesta. This lake is great for casting or trolling. Good Luck. I am sure I will run into you soon.
