We went out saturday to the main lake and the spillway, There was 3 shooters and 1 boat on the lake and we shot about 10 fish in 4 hours...When we went to the spillway there was 7 shooters on 2 boats and we didnt see 1 bighead...shot 3 fish in 2 hours. I dunno what happened to all of them. I talked to a friend of mine that was fishing there throughout the week and he said he could of killed 100's of bighead. I hope the come back soon...
