In the low light in the AM I like top waters that make a little commotion--prop baits like the torpedo and poppers like the skitter pop. Don't go to the river without some in line spinners (#2, #3 mepps) especially when the water is moving and skinny. They work regardless on the time of day. Having a good idea of the primary forage in the river helps...crawfish--tubes and crawfish imitators; minnows--twisters, slugos, senkos. I don't know how fast the river is but in faster the water a fishes window can be small so a bait that lets them know its coming (sound, flash) can improve your hookups.
