Because meadow/riparian zones link land with water, they are important for most wildlife and they support larger densities and varieties of species than other habitats. They are also used for recreation, grazing, and water development.
The watershed hosts a number of special status species including the Lahotan Cutthroat; California spotted owl, Northern goshawk and willow flycatcher; mountain yellow-legged frog; and plants including Dog Valley ivesia.
Native species include: mountain whitefish, Paiute sculpin, Lahontan redside sucker, Tahoe sucker, and mountain sucker, as well as the listed cui-ui and Lahontan Cutthroat Trout. Non-native fish include rainbow, brown trout and brook trout.
Vegetation cover includes mixed conifer forest, Great Basin sage scrub, and alpine meadows of grasses and wildflowers. Peaks are generally barren. Riparian vegetation of cottonwood, aspen, dogwood, willow, sedges and grasses grow along the river edges.
Soils above 6,500' are formed from weathered volcanic, metasedimentary and granitic rock and include glacial and alluvial deposits. Soils at 4,800-6,500' are formed primarily from weathered volcanic, rhyolitic and granitic rock and alluvial deposits.
Higher elevations and cooler temperatures in the Middle Truckee watershed lead to a growing season of 50 to 100 days in the higher elevations to 115 or more days in the lower elevations.
The watershed receives on average 30-40" of precipitation per year. However, actual amounts can differ substantially within the watershed. For example, Webber Lake receives as much as 85" a year, while Upper Dog Creek can get 14".
Streams in the Truckee River watershed appear to contain few contaminants and nutrients. However, the State has identified the Truckee River, Bear Creek, Bronco Creek, Gray Creek, and Squaw Creek as impaired for sediment. For more information, click here.
The Truckee River watershed has six major lakes/reservoirs, including Independence Lake, Donner Lake, Martis Lake and Stampede, Prosser and Boca reservoirs.
A significant portion of the watershed is located above 6,000 feet, with steep tributary streams flowing through narrow, steep-walled canyons and other tributaries entering through wider, flatter glaciated channels.
Land ranges from 5,050' at the California-Nevada state line to 10,778' at the top of Mount Rose. The Truckee River starts at about 6,200' at the Lake Tahoe outlet and is at 5,000' at state line.
The Middle Truckee River watershed - the area draining into the Middle Truckee River - covers approximately 435 square miles, or 285,000 acres of land.
The Upper Truckee flows into the southern end of Lake Tahoe. The Middle Truckee flows out of Lake Tahoe and to the CA/NV state line. The Lower Truckee flows from the state line to Pyramid Lake.
Our area of focus is the Middle Truckee River watershed. The watershed is the 35-mile stretch of river that runs northeast from Tahoe City to the California/Nevada state line, and all the tributaries that feed into this stretch of the river.
TRWC is a collaborative of agencies, private industry, local businesses, non-profits and individual citizens. Current participants are listed on the Signatories page. Any organization or individual can become a member of the TRWC. For more information, click here.
The mission of TRWC is to bring the community "Together for the Truckee". We restore, protect and enhance the Truckee River watershed.
You can become a Signatory of the TRWC. A Signatory is an organization or individual who has formally agreed to our mission, goals and programs by signing a Memorandum of Understanding. For more information, see the related document: Truckee River Watershed Council MOU.
California Flyfisher magazine, a signatory of the Truckee River Watershed Council, has done a great job organizing flow information on their web site. For more information, click here.
