Файл:Broken beaver dam on Blackwood Creek June 2014.jpg
Beaver dam on Blackwood Creek apparently broken by vandals. Beaver dams are easily crossed by trout and may serve as critical breaks for wildfires.[1][2]

Blackwood Creek (Шаблон:Lang-was), is a Шаблон:Convert[3] eastward-flowing stream originating on the southwest flank of Ellis Peak in the Sierra Nevada. The creek flows into Lake Tahoe Шаблон:Convert south of Tahoe City, California, between the unincorporated communities of Idlewild and Tahoe Pines in Placer County, California, United States.

History

Blackwood Creek was named for early settler, miner and fisherman Hampton Craig Blackwood, who settled at the creek's mouth in 1866. The area was heavily grazed and logged into the 1970s. "Blackwood Pass" at the head of the creek is named on the Wheeler Survey Report of 1876-1877.[4]

Watershed

Blackwood Creek is the third largest stream (by area and discharge) of the 63 Tahoe Basin watersheds flowing into Lake Tahoe. The Blackwood Creek watershed drains an area of Шаблон:Convert and the creek mainstem has Middle Fork and North Fork tributaries.[5] The creek mainstem is paralleled by Barker Pass Road.

Ecology

Historically, Blackwood Creek once hosted native Lahontan cutthroat trout (Oncorhynchus clarki henshawi) and other native fishes and was almost as important as the Upper Truckee River to the Washoe as a fishery. It is now a critical spawning stream for Lake Tahoe's non-native rainbow trout (Oncorhynchus mykiss).[6]

Recent evidence has shown that beaver (Castor canadensis) are native to the Sierra Nevada.[7][8] Their dams do not appear to pose barriers to trout passage.[1]
