Cedar rapids has alot of dams and you can catch flathead catfish (and big catfish) along those areas. Lots of channel catfish everywhere, drum everywhere also and they bite the same bait. I dont catch alot of bass in the cedar but then again I dont fish for those much.
Different times of the year some nice walleye and pike are caught in the cedar river and those are very good eating fish. I've caught walleye but usually by accident, I probably should fish for htose more.
