The South Fork Eel River is the largest tributary of the Eel River in north-central California in the United States. The river flows 105 miles (169 km) north from Laytonville to Dyerville /Founders' Grove where it joins the Eel River. The South Fork drains a long and narrow portion of the Coast Range of California in parts of Mendocino and Humboldt counties. U.S. Route 101 follows the river for much of its length.

Before the south bridge was finished, the north bridge was used to carry construction debris out of the realignment site on

5135-404: The ruling of the trial court since Section 10 of the special act of March 30, 1872 (Stats. 1871-2, p. 766), which concerned this boundary and was the act under which Fauntleroy acted under, authorized the survey of the theretofore unknown location of the 40th parallel north, stated that "the lines run out, marked and defined as required by this act are hereby declared to be the true boundary lines of

5214-450: The south bank of the river. The north bridge was finished in July 2009 and the south bridge completed in September 2009; the whole bypass was officially opened to traffic in October of that year. The Confusion Hill realignment bypasses the "Confusion Hill slide", a reach of unstable hillside about 1,000 feet (300 m) long and 3,000 feet (910 m) wide. Prior to the realignment this slide would shift during heavy rains, causing damage to

5293-430: The south. Emergency services for the largely unincorporated county are coordinated through Howard Forest Station , a local Cal Fire station just south of Willits. Mendocino County has nine Indian reservations lying within its borders, the fourth most of any county in the United States (after San Diego County, California ; Sandoval County, New Mexico ; and Riverside County, California ). The population ranking of

5372-472: The start of the National Wild and Scenic River section of the South Fork. The river meanders swiftly west and turns west-northwest, passing Branscomb, California . Near the city, it receives Rock Creek on the right and Redwood Creek on the left. These two stream names are a common occurrence throughout the South Fork's watershed. Afterwards, it receives its first significant tributary, Tenmile Creek, on

5451-612: The structure for recreation. The stagnant water in the lake was heated by the sun to a higher temperature than normal and severely hurt salmon and steelhead runs, as well as other aquatic and migratory life downstream. Since 2009 the dam was no longer erected. Benbow Dam was finally removed from 2016-2017 on the South Fork of the Eel River. Dam decommissioning will start to occur on the Klamath River in 2022 pending Federal Energy Regulatory Committee (FERC) approval. The 12,915-acre (52.27 km ) South Fork Eel River Wilderness

5530-434: The use of cannabis and support for its legalization . In 2009, it was estimated that roughly one-third of the economy was based on the cultivation of marijuana. The notable historic and recreational attraction of the " Skunk Train " previously connected Fort Bragg with Willits in Mendocino County via a steam-locomotive, before a tunnel collapse in 2013. Mendocino is one of three Northern California counties to make up

5609-408: The watershed is Iron Peak, at 4,491 feet (1,369 m), and the mouth of the river is at roughly 100 feet (30 m). Due to its rugged and remote location, the watershed is thinly populated. Although U.S. Highway 101 and California State Route 271 follow the river for over 70 percent of its length, there are few communities in the steep and narrow, forested canyon of the South Fork. Towns along

5688-403: The watershed, including Low Gap Creek, Redwood Creek, Rock Creek, and Red Mountain Creek. Historic logging activity in the South Fork watershed has stripped steep hillsides bare of vegetation, resulting in chronic erosion problems. Historically, South Fork Eel River water had an unusual translucent blue-green hue for most of the year. Increased turbidity levels caused by erosion has transformed

5767-410: The winter months, the South Fork Eel receives another tributary called Redwood Creek on the left bank, as it bends north and then west around the community of Redway, California , which is located on a plateau east of the river. The river then passes through another rugged canyon, flowing northeast, then passes the towns of Phillipsville and Miranda which are to the east of the river. West of Miranda,

5846-429: Was 1,747 cubic feet per second (49.5 m /s). Peak discharges of 64,700 cubic feet per second (1,830 m /s) were recorded in both 1912 and 1913, while for 1940, the peak was 55,600 cubic feet per second (1,570 m /s). The Leggett stream gauge began operating in 1965 and is still in use. An average discharge of 774 cubic feet per second (21.9 m /s) was recorded here from 1966–2010. The highest flow recorded

5925-414: Was 20,000 while coho averaged 16,000 at Benbow Dam in the 1930s. Since then, the population has steadily declined, with a current population of roughly 1,000. The reason for the decline is the high amount of silt carried into the river by logging activity and road construction. The silt has filled stream pools and caused higher turbidity, which has harmed fish. The South Fork is said to be the last habitat in

6004-411: Was 39 years. For every 100 females there were 98.9 males. For every 100 females age 18 and over, there were 97.1 males. The median income for a household in the county was $ 35,996, and the median income for a family was $ 42,168. Males had a median income of $ 33,128 versus $ 23,774 for females. The per capita income for the county was $ 19,443. About 10.9% of families and 15.9% of the population were below

6083-401: Was 72,700 cubic feet per second (2,060 m /s) on 4 January 1966. A higher peak flow of 78,700 cubic feet per second (2,230 m /s), on 22 December 1964, before the stream gauge was in place, was determined using flood stage height data and floodmark measurements. The minimum discharge recorded by this gauge was 7.3 cubic feet per second (0.21 m /s) on 4 August 1977. For Branscomb,

6162-601: Was designated in 2006, stretching along portions of the South Fork Eel and extending westward to the Pacific Ocean. The wilderness area borders that of the King Range Wilderness , which is said to be the "longest stretch of undeveloped coastline in the United States outside of Alaska". The river provides wildlife habitat for preservation of rare and endangered species including cold freshwater habitat for fish migration and spawning. The South Fork Eel

6241-410: Was historically rich in salmon and other species of anadromous fish, and has been known as the "most productive sub-basin for anadromous fish". The main anadromous fishes in the South Fork are chinook salmon , coho salmon and steelhead , and it is said that "the South Fork Eel River once supported about half of the total coho run for the State of California". Historically, the population of chinook
