The Truckee River is a river in the U.S. states of California and Nevada. The river flows northeasterly and is 121 miles (195 km) long. The Truckee is the sole outlet of Lake Tahoe and 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.
It supports a large sport fishing population each year. NDOW stocks a total of 105,000 trout per year. 70,000 of those are native Lahontan cutthroat trout (Oncorhynchus clarki henshawi) and the rest are non-native Rainbow trout (Oncorhynchus mykiss). The Truckee also boasts a healthy, self-sustaining non-native Brown trout (Salmo trutta) population.
