Well, I may be wrong, but I believe that the fish that we catch in front of Hoaks in May are always in the post-spawn & pre-summer phases. I think that they slowly move away from the spawning areas, and then hang out off of the flats to munch on spawning baitfish. With the water temps only in the mid- to upper-40s, I think that is still too early for the good night bite.
Spring came early this year, and the lake didn't freeze, but we can't be so far ahead of schedule that we have completely passed by the shallow water, rapala night bite.
I think (hope!) that we are still ~1 week in front of the good night bite vs. beyond it.
