With a total length of 205 miles, the Carson River flows through one county in California and four counties in Nevada. The river empties into the Carson Sink, an endorheic basin and was named for Kit Carson, a guide for the John C. Frémont expedition in 1844. It is also home to different species of birds like tundra swans, white-faces ibis and American white pelicans, fish like rainbow trout and brown trout and the North American beaver as well.
