I don't fish Belton but on the lakes I do fish, shad have been tough to catch for me this year. Like every other fish, the high(er) water, no winter, inflow, outflow has changed pretty much every pattern we have become accustomed to the last few years. I've yet to find a consistent daytime spot to catch shad on any of the lakes I fish. I've started catching all of my shad by anchoring up in a cove and dropping a green light at about 5am. If you are in a good area you will have all the shad you could ever catch under your boat in about 10 minutes. A good many will be threadfin shad, but I don't mind fishing with big threadfin.
