Overview

The Marble Bluff Dam and Pyramid Lake Fishway, Washoe Project, was constructed between 1973 and 1975. Marble Bluff Dam is located on the Truckee River approximately 50 miles downstream of Reno, Nevada and approximately 3 miles upstream of Pyramid Lake. It is a zoned earthfill structure with a height of 22 feet and crest length of 1,622 feet, and it has a capacity of 19,700 cubic feet per second through the spillway.

It functions to halt erosion within the Pyramid Lake Paiute Tribe’s Reservation and controls water used by the Pyramid Lake Fishway. The Pyramid Lake Fishway, with a capacity to pass 50 cubic feet per second, extends from Marble Bluff Dam about 3 miles and improves the ability of the cui-ui and Lahontan cutthroat trout to migrate to their spawning habitats above the dam in the Truckee River.
