The Truckee River Operating Agreement (TROA)

The TROA was made available to the public as an appendix to the Final Environmental Impact Statement and Environmental Impact Report (EIS/EIR). After a process that included public comment and response, this EIS/EIR was released on January 23, 2008. The EIS/EIR concludes that TROA has no significant adverse environmental effects, and that its implementation is the superior environmental alternative. This is rare in that most actions considered in EIRs have environmental consequences that are balanced against benefits, whereas this EIS/EIR found TROA to be the best action for the environment.

The release of the final EIS/EIR is a major step in a sequence of steps required before TROA can be implemented as provided for in the Truckee-Carson-Pyramid Lake Water Rights Settlement Act of 1990 (PDF, 7.6MB) (�Settlement Act�). After due consideration, the Secretary of the Interior of the United States signed a Record of Decision (ROD) and the State of California signed a Notice of Determination (NOD) stating that an EIS/EIR has been prepared and that it determined that implementing TROA will not have a significant adverse effect on the environment. The NOD will be filed with the Governor�s Office of Planning and Research where it will be kept for public review for at least one year. TROA was signed by the Secretary of the Interior and by the Resources Secretary of the State of California on September 6, 2008. These and other steps including the approval of the Orr Ditch Court in the U S District Court in Reno and Truckee General Electric Court in the US District Court in Sacramento and the approval of water rights change petitions by the California State Water Resources Control Board (SWRCB) must be completed before TROA can be implemented.

The parties who signed TROA were The U.S. Department of the Interior, U.S. Department of Justice, States of California and Nevada, Pyramid Lake Paiute Tribe, Truckee Meadows Water Authority, and other entities in California and Nevada.

The Settlement Act (PDF, 7.6MB) and TROA (PDF, 20 MB) will: 1) allocate the waters of the Truckee River, Carson River, and Lake Tahoe basins between California and Nevada; 2) enhance conditions for threatened and endangered fish species throughout the Truckee River basin; 3) increase drought protection for Truckee Meadows (Reno-Sparks metropolitan area); 4) improve river water quality downstream from Sparks, Nevada; 5) enhance instream flows and recreational opportunities in California and Nevada; 6) settle long standing litigation over water rights to the Truckee River; and 7) lift the SWRCB's 1972 moratorium on water rights applications in the affected region.

Staff at the California Department of Water Resources (DWR) Central District Office has been providing technical assistance to the Office of the Chief Counsel during the negotiation of TROA and associated approval processes. For additional information or for a copy of the Draft TROA, please visit the U.S. Bureau of Reclamation�s website at: http://www.usbr.gov/mp/troa/ or contact John Sarna (jsarna@water.ca.gov) at the Department of Water Resources, Central District Office.
