The water is probably still cold there so on sunny days the shallows warm up and they move shallow to take advantage of the warmer temps. Clear water fish are more vulnerable and spook very easy. I use tiny hand tied jigs 1/80-1/48 with a #10- #12 hook with 2lb. line. I tie these little baits as small as I can, some are less than an inch long. Position yourself so they can't see you before you cast and retrieve slowly with occasional twitches to make it look alive. Tiny baits are the key.
