The Martis Creek Project is located on Martis Creek, a tributary of the Truckee River, about 32 miles southwest of Reno, Nev. It is comprised of an earthfill dam, creating a reservoir with a gross storage capacity of 20,391 acre-feet. The project provides flood risk management and recreational benefits, and also retains the design purpose of future water storage. A population of approximately 72,000 is within the inundation zone for Martis Creek Dam, and includes large portions of the cities of Reno, Sparks and Truckee Meadows.
The project was completed in 1972, and consists of a 113-foot-high rolled zoned earthfill dam across Martis Creek, an upstream impervious blanket, several post-construction seepage control features, an outlet works conduit, and a detached concrete lined spillway in the left abutment. The inlet structure and control house are located near the upstream toe of the dam.
