I go camping every spring at kathio, we catch more fish in the river than in mille lacs, from the dam in the park you can catch walleyes, bass, northerns, muskies, sunnies, and even some carp and dogfish. There is a boat launch right in the state park fir the river, the river averages about 5-10 feet, but there are some spots that get real shalo if you head south on the river. I hope this helps.
