Salmon River (California)

The Salmon River is a 19.6-mile-long (31.5 km) tributary to the Klamath River in western Siskiyou County, California.

The river has its origins in the high mountains of the Trinity Alps, Russian Mountains, and Marble Mountains (all sub-ranges of the larger Klamath Mountains). The Salmon River comprises two forks, the North Fork and the South Fork, which join at the hamlet of Forks of Salmon, California to form the mainstem Salmon River. A large tributary stream, Wooley Creek, joins the mainstem Salmon River about 4 miles (6 km) from its mouth at Somes Bar, and is nearly as large as the North Fork. The lower portion of the Salmon River's southwestern divide defines the boundary of Siskiyou County and Humboldt County.

The river's 751-square-mile (1,950 km²) watershed is entirely within the Klamath National Forest, and less than 2 percent of the land area is privately owned. Nearly half of the watershed is federally protected wilderness area, including portions of the Trinity Alps Wilderness on the south, the Russian Wilderness on the east, and the Marble Mountain Wilderness on the north. Another twenty-five percent of the watershed is designated as Late Successional Reserve under the Northwest Forest Plan and is managed to enhance and retain old growth forest characteristics and habitat.

Unlike most other large California rivers, the Salmon is completely free flowing, with no dams or significant flow diversions of any kind and no hatched and planted fish. It is one of the most pristine areas in the Klamath River system and one of California's most pristine rivers. It retains the only viable population of wild spring Chinook salmon in the Klamath watershed and offers some of the best West Coast habitat for salmon, steelhead, green sturgeon, rainbow trout, Pacific lamprey, and other fish. The mainstem Salmon River, its North Fork, South Fork, and Wooley Creek are part of the National Wild and Scenic Rivers System, having been designated by Secretary of the Interior Cecil D. Andrus in January 1981, who was acting on California governor Jerry Brown's petition to add the rivers to the federal Wild and Scenic Rivers System.

Forest fires are one of the largest threats to the river and its watershed. Fires are a natural part of this ecosystem, but are not fueled by logging slash but rather the huge fuels accumulated through decades of logging restriction inadequate fire suppression efforts and therefore fires burn much hotter, more intensely, and more frequently than they would otherwise naturally burn. The waste of burned timber not logged after fires is in the tens of millions of board feet and lost dollars that would not only enhance the regrowth of the once burned forest but also provide revenues to mitigate the hundred million dollars the most recent fires in 2013/14 cost. The trees rot and are eaten by bug infestations due to environmental influence over the Usfs leading to inaction and delay and lost timber revenue taxes and jobs. Large fires in 1977, 1987, 2002, 2006, 2008, and 2013 have contributed to increased erosion, causing sediment buildup in the river and its tributaries. The excessive sediment degrades the habitat of aquatic organisms, particularly for coho salmon, Chinook salmon, sturgeon and steelhead trying to spawn.
