Heenan Lake contains a fish population of a federally listed threatened trout species, the Lahontan cutthroat trout (CT-L). Heenan Lake provides an important brood stock source of CT-L used in many waters throughout the State of California for the California Department of Fish and Game (Department) hatchery system. Heenan Lake is a California Fish and Game Commission designated wild trout (1983) and heritage trout (1999) water, and provides an important sport fishery for anglers from throughout
the western United States.
Our El Dorado Chapter is planning a fishing outing in September or October. Heenan is only open for fishing on Friday Saturday and Sunday in September and October. The Wild Trout personnel have prepared a management plan for Heenan which explains the use of Heenan and indicates propagation process for the Lahonton Cutthroat. See the Management Plan
