Have you checked the docks up to the bridge on gumlog. I don't know what the water temp is there but it is running 48 to 50 degrees on the hill. If you have side finding capabilites with your fish finder check docks around the shallow water. Sometimes crappie do the unexpected....the flat above the bridge warms up quicker and you may find crappie in that area. The rip rap at gumlog bridge may hold crappie there also. Hope this helps..tommy
