Catnip Reservoir is located in northern Washoe County on the Sheldon National Wildlife Refuge, approximately 50 miles west of Denio Junction. Catnip was constructed in 1910 and was used as an irrigation source for the IXL Ranch, its secondary function was to provide a waterfowl nesting area. The 22 surface acre impoundment stored 220 acre-feet of water when first constructed, however the capacity is currently much less due to siltation. Catnip Reservoir was opened to fishing for the first time in 1998. The only trout species present in the lake is the Lahontan cutthroat trout. The reservoir receives little pressure due to its short season and remoteness. Primitive camping at the lake. Catnip Reservoir, its tributaries and outlet stream are open to fishing from the second Saturday in June through November 15, any hour of the day or night. Federal regulations for the Sheldon National Wildlife Refuge state that anglers may bank fish, fish by wading, or use non-motorized boats, boats with electric motors, float tubes and similar flotation devices.
