Butts,
The tailwater is just about impossible to wade and very impractical to throw a fly. Rip rap full of line and other junk. Also, the current can get tricky with the H20 running. I always imagine being there throwing a big clouser or the like, but I just don't think it would work out. Maybe at the right spot at the right time? When it is on the fishing can be CRAZY. Crazy with people and crazy with fish. There is always room to fit in though. I Always fish there with spinning gear. Its a ton of fun in the spring b/c you never know what will be at the end of your line. A slab crappie, nice eye, a freight train hybrid, silver bullet, paddle fish, #10 buffalo, or maybe even a catfish. Generation helps considerably. Have had many good days there. Usually hit a few small cricks and tribs of Truman in search of Mr. Crappie also.
The hardest aspect of the white bass run is deciding where to go. We spend a lot of time with the fly on the L. Sac and the James (looking for those 1st big females), but also give attention to one other trib of Stockton! Hit the pot hole, Beaver, and Swan as well. So many places in the area to run to its hard to pick only one. Haven't ventured to Caplinger or Theodosia yet but plan to. Sure there are many other spots to hit too, but throw mushrooms, turkey, and small jaws into the mix and I've got a big mess.
Best fishes!!
