The Silver Creek drainage is located on the eastern slope of the Sierra Nevada Range, in Alpine County, California.

Document Description
The Paiute cutthroat trout (Oncorynchus clarki seleniris) is a federally listed threatened species. Silver King Creek is part of the Paiute cutthroat trout's historic range but is currently populated by hybridized non-native trout that could threaten the existence of pure Paiute cutthroat trout located above Llewellyn Falls if these populations were inadvertently mixed. Hybridization with non-native fish is a primary threat to the subspecies. The fish present in reaches downstream from Llewllyn Falls to Silver King Canyon are a genetic mixture of introduced rainbow (Oncorynchus mykiss), Lahontan cutthroat (Oncorynchus henshaw), golden trout (Oncorynchus aguabonita), and native Paiute cutthroat trout. The proposed project would geographically isolate pure populations of Paiute cutthroat trout. CDFG, in colaboration with USFWS and USFS, proposes to remove all non-native hybridized trout in Silver King Creek, in Alpine County, California, from Llewellyn Falls to Silver King Canyon, using the piscicide rotenone.
