Re: Middle Allegheny River Depths - Map/Chart Avail.?
You will not find a map of the Allegheny that details depth very far above lock 9 (East Brady-Bradys Bend area). The shallows of the Allegheny change yearly, sometimes more frequently, depending on rainfall.
My advice is to find someone in the Tidioute area who knows the river up that way and have them take you out. That area can be tricky and you can get into big trouble in a hurry if you take the wrong path through or around the numerous islands. I'd offer, and have been from President all the way to Warren, but I cannot say I know it all that well. I just know how to read the water and make the best of it.
It's critical to lLearn how to read the river. V's, chutes, riffles, swirls created by large rocks under the surface. That's my best advice. Never rely on a sonar unit while running. It's all about reading the water, much like it is in a kayak or canoe.
Best of luck with that new jet. They are a blast.
