Located approximately five miles south of Gardnerville, Nevada, or approximately sixteen miles south of Carson City, the Lahontan National Fish Hatchery is just one part of the Lahontan National Fish Hatchery Complex. In addition to the Hatchery, the Complex includes the Bluff Fish Facility and the Nevada Fish Resource Office.

The Complex plans and implements coordinated management and recovery activities for the endangered Cui-ui of Pyramid Lake and the threatened Lahontan cutthroat trout. Marble Bluff Fish Facility is critical to moving the endangered Cui ui around the dam. A "fish lock" acts like an elevator that brings the fish up to the river so that they can spawn in the river. The best time to visit is during spring spawning runs, when the fish are actively making their way up the "fish lock". The hatchery is open daily from 7:30 a.m. to 4:00 p.m. Environmental education tours are available by reservation.

Lahontan cutthroat trout are raised at the Lahontan Fish Hatchery for recovery purposes and for stocking for recreational fishing. Each year the hatchery releases about 600,000 Lahontan cutthroat trout into Pyramid and Walker Lakes.
