I have been fishin the main lake lately and have been catching fish so i decided to try up the glaize last trip out and things were very slow and got worse the further i went up but that will change shortly,usually when they drop the lake to winter pool and it is stable for a few days they move way up the glaize arm and spread out on the flats(if the water is stained)i guess its one of their first movements preparing for the upcoming spawn.Just because the water is cold dont overlook shallow water especially on warm afternoons the fish are up there feeding big time,i always catch fish in 8' or less starting sometime in january and usually they are full of shad so that proves to me that all the shad in the lake dont stay deep either.Right now i would try the main lake then in a few weeks try up one of the creek arms just find a flat with some structure and a creek/river channel and give it a shot.
