South Twin Lake is dominated by rough fish like common carp and bigmouth buffalo. There are very few sport fish present and even fewer of quality size. However, for those that like to fish for bullhead South Twin is a good option. The bullheads are around 7 to 8 inches, but there are a lot of them.(2017)
