Try the basin or middle where it is the deepest. When there is alot of snow cover , mid winter crappies will suspend in deep water. I have been catching them suspended at 8 Fow in 12-15Fow . Will be different according to basin depth on a given waterbody , but the schools will usually roam the basin in mid winter . Ifya can get a depthmap, do so and fish the basin closest to where ya catch em in spring.
