Any tips on fishing fast moving river? I can sight the fish but I cant get them to bite. Im not sure what type of fish they are but I am certain that they are spotted bass or large mouth bass because of the black stripe on the side.

What's the forage?

Are you boat or bank fishing? If in a boat, do you know how to "slip" a river system? This is simply a technique of boat control where you keep your bow directed up-stream and run your engine just fast enough to slip backwards, slower than the current. This allows you to get your bait down to the fish - which are located in eddies and backwaters - and keep your bait in the strike zone longer. If you unfamiliar with this system, google Dan Gapan.

Another thing to consider, the water on the top is moving faster than the water at the bottom.

I don't fish rivers anymore but I do fish the ICW which is like a river and inlets.  Our inlet is about the fastest water in South Florida, the Coast Guard has reported 6-12 knots depending on tide, other inlets run about 4 knots.  True about the water direction, at times near the shore it can run in the opposite direction, and that's when it gets fun.  I'm fishing about 10- 15' of water, I like to throw against the current with a bait that gets down low like jig, be real careful not to snag which I've done hundreds of times, but that's where the fish are.
