Hey Ron,
Sorry to hear about the poor catching. It seems to be that the warmer the weather, the deeper most people fish. The bait of choice lately has been fathead minnows. Usually the power bait becomes better as the weather gets warmer. I had been hearing some pretty good reports lately, but maybe the fishing pressure gets to be too much on some days?
I wish I had a better idea of when they stock and how often they stock, but it seems to be a secret.
Good Fishing,
Mike
