Silver King Creek Basin is a tributary to the East Carson River Watershed. The headwaters start in the Carson-Iceberg Wilderness Area in the Humboldt-Toiyabe National Forest.
The creek contains the Paiute cutthroat trout, a species listed as threatened under the Endangered Species Act of 1973.
In the 1900s the Paiute were moved above a natural barrier by a sheep-herder. One year later, their historic watershed had rainbow trout introduced and the populations hybridized.
The only remaining stock of pure Paiute was above the natural barrier. Currently, Lahontan cutthroat trout, non-native rainbow trout and hybridized populations inhabit the Paiute cutthroats historic habitat.
