Ive seen alot of people posting about horsedshoe dam and wanted to throw this out for all to hear. Hopefully it helps you. I have not fisshed Horsehoe dam but hunt up there all winter. Very good duck hunting below the dam. Anyway I sat and watched an older gentleman absolutely slay the faltheads there a few years back nobody else fishing that night caught anything decent. He told me the following. 2 keys. 10 You must fish live carp 10-12 inch in size and 2 you need surf casting gear because the fish are in a hole out in the middle of the river. its a good distance and ONLY surf gear will allow you to reach the hole. The big flats sit down in that hole and ambush the carp as they are swept in. I watched him catch one after another really big fish. Hope this helps.
