My first response was stupid; here is a more educated approach: Simple single dimple-blade spinner bait; fire/tiger or yellow in color, 1 1/4oz size try pulling it past deeper structure. It may be challenging getting a bite in shallower areas in those temps unless you have some form of current such as a drain out with warmer current. Most bass will hold deeper until things warm up. Is it legal to fish bass now in your area?
