The Truckee River is a river 140 mi (225 km) long in northern California and northern Nevada in the United States. It drains part of the high Sierra Nevada, emptying into Pyramid Lake in the Great Basin. Its waters are an important source of irrigation along its valley and adjacent valleys. The water is quite clear near Lake Tahoe, but the river turns muddy by the time it passes Reno, Nevada.

Description

The river, here alternatively known as the Upper Truckee River, originates from the mountains south of Lake Tahoe, flowing into the lake at its south end before issuing once more from the lake's northwest side near Tahoe City, California. It flows generally northwest through the mountains to Truckee, California, then turns sharply to the east and flows into Nevada, past Reno and Sparks and along the northern end of the Carson Range. At Fernley it turns north, flowing along the east side of the Pah Rah Range and entering the southern end of Pyramid Lake, a remnant of prehistoric Lake Lahontan, in southern Washoe County in the Pyramid Lake Indian Reservation.

Uses of the river

Like other rivers in the western United States, the Truckee's flow is highly regulated with most of the river water fully allocated via water rights. Disputes occur among those claiming the water. In the early 20th century, waters of the river were diverted as part of the Newlands Reclamation Act. Currently the Truckee-Carson Irrigation District supervises the diversion of approximately one-third of the river flow at the Derby Dam to the Lahontan Valley to irrigate alfalfa and pastures. Its water is also supplied to the resort communities surrounding Lake Tahoe, the greater metropolitan area of Reno and Sparks, and the Pyramid Lake Paiute Indian Reservation. The U.S. Fish and Wildlife Service uses some of the water to induce spawning of the endangered fish cui-ui and to provide drought relief. The river is heavily used for recreation, including whitewater rafting and fly fishing. A common rafting run is the River Ranch Run. Starting from the outlet gates at Lake Tahoe stretching approximtely 3 miles, the run ends at the River Ranch Resturant. These rapids are almost all class 1 and class 2. This is also the main run for commercial rafting companies.

Hydrology and water quality

The Truckee River near Truckee, California

Because of the endangered species present and due to the fact that the Lake Tahoe Basin comprises the headwaters of the Truckee River, the river has been the focus of several water quality investigations, the most detailed starting in the mid-1980s. Under direction of the U.S. Environmental Protection Agency, a comprehensive dynamic hydrology transport model was developed by Earth Metrics Inc. The model's name was subsequently changed to DSSAM, and it was applied to analyze impacts of a variety of land use and wastewater management decisions throughout the 3120 square mile Truckee River Basin and provide guidance in other U.S. river basins^[1]. Analytes addressed included nitrogen, reactive phosphate, dissolved oxygen, total dissolved solids and nine other parameters. Based upon use of the model, some decisions have been influenced to enhance riverine quality and aid the viability of associated biota. Impacts upon the receiving waters of Pyramid Lake were also analyzed.
