Carson River Park

The Carson River is a northwestern Nevada river that empties into the Carson Sink, an endorheic basin. The main stem of the river is 131 miles long although the addition of the East Fork makes the total length 205 miles, traversing five counties: Alpine County in California and Douglas, Storey, Lyon, and Churchill Counties in Nevada, as well as the Consolidated Municipality of Carson City, Nevada. The river is named for Kit Carson, who guided John C. Frémont's expedition westward up the Carson Valley and across Carson Pass in winter, 1844. The river made the National Priorities List on October 30, 1990 as the Carson River Mercury Superfund site due to investigations that showed trace amounts of mercury in the wildlife and watershed sediments.
