I got bored and drove over a few times several weeks ago knowing I was too early for white bass. I caught a few LMBs. One day, about a month ago, there were a few guys catching either white bass or crappie . . . I was standing too far away to tell but they looked like white bass . . . just to the right of the kayak launch by about 20 or so yards.
My guess is these were males. They'll come up into rivers and creeks earlier, the females follow up when the water warms up more, what, 55 to 60 degrees is optimal.
My guess is white bass will be "late" this year with the repeated cold fronts holding temps down.
