I use to fish LAK quite a bit until they let the tiger muskies die out. They have started stocking it again but due to the large number of walleyes, and smallmouth bass they are having trouble getting them started again. The lake had (and assume still does) have a decent population of eater sized walleyes and lots of small with a few big smallmouths. After the tigers died out the green sunfish population boomed to levels similar to pre tiger muskie levels, most are small, I don't know if this is still the case. There are very rare largemouth bass, and the lake probably still has some trout, mostly rainbows with a few browns mixed in. Hope this helps.
