Flathead Structure

Well I got all the stuff for it, now I have to go and find them. I was going to try either the lock in Charleroi or the one in Maxwell. When fishing the locks, do you fish downstream of it or upstream of it? I will be fishing from shore so is the any difference in access? Any other decent places to start out at, or should I spend a few nights trying to find a decent place. Thanks
 
I would also like to be able to fish for other species there, could care less what but I need to keep myself busy while I wait.

Yes I did know that, I was hoping to go out, at the moment we are, but if the water is still cold we won't be, I do know they are not cold water fish at all

I mainly fish just below the dams, bridge supports and deep holes. Not saying fish arent at other areas on the rivers but thats personally what I fish the most. Fish live and if you dont get a run after an hour or so cut the belly open and give it a shot.
