Newlands Project

The Bureau of Reclamation has a contract with the Truckee-Carson Irrigation District to operate and maintain the Newlands Project on behalf of the Federal government. The Newlands Project has features in both the Carson and Truckee River basins with the Truckee Canal allowing interbasin diversions from the Truckee River to the Carson River. The Newlands Project is made up of two divisions, the Truckee Division and the Carson Division. The Truckee division includes:  Lake Tahoe Dam, Derby Diversion Dam, the Truckee Canal and irrigation delivery system for service to approximately 5,000  acres of irrigated lands. The Carson Division includes: Lahontan Dam, Lahontan Power plant, Carson River Diversion Dam and canals, laterals, and drains for irrigation of approximately 55,000 acres of farmland.
