Truckee River

The Truckee River is a major western Nevada stream. It begins at Lake Tahoe, runs through the city of Reno, and terminates at pyramid Lake. The Truckee river is about 120 miles long and is the only stream that comes out of Lake Tahoe. One of the most popular recreational activities on the Truckee River is rafting and kayaking. The city of Reno even has a whitewater park that beginning to advanced kayakers can enjoy.

The Truckee River basin (hydrographic region 6) covers over 4,700 square miles and straddles the California-Nevada border. The Truckee River Basin includes the following hydrographic areas: Winnemucca Lake Valley, pyramid Lake Valley, Dodge Flat, Tracy Segment, Warm Springs Valley, Spanish Springs Valley, Sun Valley, Truckee Meadows, pleasant Valley, Washoe Valley, Lake Tahoe Basin, and the Truckee Canyon Segment. Major cities in the Truckee River Basin are Truckee, California, and Reno and Sparks, Nevada.

Truckee River Operating Agreement

The Truckee River supplies water to a diverse group of water users: power generation, municipalities, industry, and agriculture as well as being the primary source of water for pyramid Lake. As Truckee River water is allocated upstream of pyramid Lake, it has the potential of affecting lake levels and the endangered fish that live in pyramid Lake. The Truckee River Operating Agreement (TROA) is a major part of Public Law 101-618, the Truckee-Carson-pyramid Lake Water Rights Settlement Act of 1990. TROA is a foundation for balancing the allocation of water rights to many different water users in the Truckee River Basin.
