The reservoir is usually ice-free by mid March. Rainbow trout begin patrolling the shorelines looking for food and a place to spawn as soon as the ice comes off and can provide great fishing throughout March and April. Most popular baits, lures, jigs and flies can produce good fishing. Wipers also start to get active and typically seek out the warmest water in the shallows. For wipers, use lures and flies that imitate chubs and crayfish. As the spring progresses into May, trout feed actively on the surface early and late, while moving into deeper water during the day. Smallmouth bass will also get more active in later spring, while wipers become more nocturnal. Consult the Otter Creek Reservoir entry on the Fish Utah map for more details on spring fishing.
