Catnip Reservoir - Denio, NV

Catnip Reservoir, situated within the Sheldon National Wildlife Refuge near Denio, Nevada, functions as a critical conservation and specialized sport fishery. This remote impoundment is managed primarily for its genetically significant population of native Lahontan Cutthroat Trout (Oncorhynchus clarkii henshawi). Due to its pivotal role in species restoration, stringent regulations are imposed, often mandating catch-and-release angling exclusively with artificial lures and single barbless hooks, and limiting the fishing season (e.g., September 1 – November 15).

Angling methodologies are predominantly focused on fly fishing, optimized for Lahontan Cutthroat Trout. Large streamer patterns (e.g., Woolly Buggers, baitfish imitations in dark or olive hues) retrieved aggressively along structural features and weed lines are highly efficacious. Nymphing with imitative patterns (e.g., large midges, caddis, mayfly) and opportunistic dry fly presentations during active entomological or terrestrial hatches (e.g., Callibaetis, damsel flies, grasshoppers) also yield significant results. Access is strictly controlled within the refuge via unpaved roads, and boating is restricted to non-motorized or electric motors. Anglers are unequivocally mandated to consult current U.S. Fish and Wildlife Service (USFWS) and Nevada Department of Wildlife (NDOW) regulations concerning all specific provisions, crucial for the sustained ecological integrity and recreational quality of this unique and vital native trout stronghold.
