Flatheads moving on up

[Fredrick]

Looks like the Flatheads are moving there way up the D now.

I'm curious if they will move their way up threw the trout water ?

Not sure about this. When flatheads got into the James River in VA some years ago many locals regarded their effect on SMBs as disastrous. However, I don't know how far up that river they eventually migrated (maybe stopped by a dam?). Also, they're native to the Ohio River drainage. Are they prevalent in the colder water below Kinzua and is there evidence they predate on trout in that colder water?
