The spill way is a great place to bowfish! There is two places to fish one is near the dam and you will have to walk down a little ways to get out of the heavy current but we seen pleanty of rough fish coming up to the surface and when you can walk no further because of a creek you can go to the other spot which is the boat landing right off the highway near the suspension footbridge under that is a wing dam that you can bow fish off of if the water is low enough this is where we seen the most gar but be careful as the rocks are hard on tips. Near the boat landing and back in that slough we seen several carp surface.
Depending on when you go you might get medic to meet you down there if he is not working.
Have fun and let us know how you did.
