Not sure what you are talking about. Do you mean when rivers rise suckers will bite better?
Went today for about 3 hrs. First place I fished mouth of creek no bites for 1-1/2hrs, 2nd place I went to a spot I caught chubs on the Eel but no creek and not one bite. The Wabash was 2-3 times as muddy as the Eel, the creek into the Wabash was pretty clear. Forgot to take grill thermometer along to test temp of the water but I imagine its still under 50, was 43 last weekend.
