Look for the first break coming from shallow water. Your water temps suggest that the fish will be in pre spawn. When fishing for the eyes, fish in the evening right before dusk and 2-3 hours after sunset. Casting long skinny lures, Rapalas, in shallow water. Don,t be afraid to stay in the shallows. Have caught many an eye in less than 3 ' of water at night. You may actually hear them rolling on the surface like carp.
