The Truckee River Flood Management Authority (TRFMA) is responsible for oversight and implementation of the Truckee River Flood Management Project (Flood Project). The agency is a joint powers authority created in 2011 by an Interlocal Cooperative Agreement executed among Washoe County, the City of Reno, and the City of Sparks. Nevada Senate Bill 175, approved in June 2009, served as the basis for the new flood authority (refer to Chapter 477, Statutes of Nevada 2009, Page 2735 for more information).

The agency’s primary mission is to plan, design, build, operate and maintain infrastructure to reduce flood damages, safeguard public health, and create a more resilient community. TRFMA serves as the official Local (Non-Federal) Sponsor working with the Corps to evaluate flood risk management alternatives and secure federal funding (via Congressional authorization and appropriations) to construct the Flood Project. In coordination with various federal agencies and local emergency managers, TRFMA also operates and maintains a network of stream gages that monitor river stage as part of a regional Flood Warning System.
