There is a freshwater reservoir in Wahiawa on the island of Oahu. It is called lake Wilson by the locals. It has large mouth, small mouth, and peacock bass. I've cought large mouth and peacock bass there. the fishing there is differant on a day to day basis. The bigest problem is the rain run off that dirtys the water up pretty good, but the fish are there and fun to catch. Also, there are channal catfish that are easy to catch if the bass are not bitting that day.
