I try to pick up stuff too, but some places you can fill up multiple bags and it becomes too much.
You'll enjoy it though if the fish are biting. A wide variety of fish. Fishing off the wall can be productive and also wading. The only problem with fishing off the wall is if you hook a decent fish you'll have to walk it down and have someone else land it, so I usually prefer wading unless there's nobody on the walls. Lots of good water downstream too, and if I plan to fish there most of the day often times I'll park at the bridge and walk up to the dam, and fish everywhere in between. Live minnows should produce everything in that river, just make sure they stay alive though.
