Crooked lake last year was very good for perch and walleye. All year long the perch bite was on hard. The walleye really turned on late in the year. We did the best on the east end of the lake closer to the river mouth. I know a freind who is a biologist and they did a study on crooked this year and found that there was alot of kill because of the lack of oxygenated water. Not as many walleye as perch but tons of white fish. So i don't know how that will effect this years ice fishing out there, i don't fish there in the summer but heard the walleye were hot ne way hope i was of some help.
