TheYuba Riveris atributaryof theFeather Riverin theSierra Nevadaand easternSacramento Valley,in theU.S. stateofCalifornia.Themain stemof the river is about 40 miles (64 km) long,[2]and itsheadwatersare split into three major forks. The Yuba River proper is formed at the North Yuba and Middle Yuba rivers' confluence, with the South Yuba joining a short distance downstream. Measured to the head of the North Yuba River, the Yuba River is just over 100 miles (160 km) long.

The river drains 1,345 square miles (3,480 km2),[2]mostly in the western slope and foothills of the Sierra Nevada. The average runoff of the Yuba River basin is approximately 2,303,000 acre-feet (2.841 km3) per year,[4]providing about one-third of the flow of the Feather River, and 10 percent of the flow of theSacramento River,which the Feather ultimately drains into. Since the early 20th century, irrigation and hydropower diversion projects have gradually reduced the river's flow.

The river's name comes from the local tribe, theNisenan,word for "waterway," 'uba seo.'[5]It is spelled in early records as "Yubu" and applied to the river by 1844.[6]Some claim the name is a variant of Spanishubaoruva,referring to grapes found growing along the banks of the river.[7]

Course

[edit]

North Yuba River

[edit]
Main article:North Yuba River

The North Yuba River, 61.1 miles (98.3 km) long,[2]rises atYuba PassalongCalifornia State Route 49,near the eastern boundary of theTahoe National Forest.It flows southwest then west through a 3,000-foot-deep (910 m) canyon past the communities ofDownieville(where it receives theDownie Riverfrom the north) and Goodyears Bar. Its main tributaries, Canyon Creek and Slate Creek, join from the north shortly downstream of there. The river turns south nearClipper Millsand flows into the 4,800-acre (1,900 ha)New Bullards Bar Reservoir,impounded by 645-foot (197 m)-highNew Bullards Bar Dam.About 5 miles (8.0 km) below New Bullards Bar Dam, it joins with the Middle Yuba River to form the Yuba River.[8]

Middle Yuba River

[edit]
Main article:Middle Yuba River

Originating in a bowl-shaped valley in Moscove Meadow, the 55.4-mile-long (89.2 km) Middle Yuba River[2]flows north intoJackson Meadows Reservoir,then turns west, soon entering a steep gorge. The majority of the river demarcates the boundary of Sierra County in the north and Nevada County in the south. It receives Kanaka Creek from the north and is then interrupted by the Our House Diversion Dam, which diverts water from the Middle Fork to the North Fork at New Bullards Bar Reservoir. Below the dam, it continues flowing west, receives Oregon Creek from the north and intersectsCalifornia State Route 49about 2 miles (3.2 km) northwest ofNorth San Juan.About 7 miles (11 km) downstream it joins with the North Yuba River.[8]

South Yuba River

[edit]
Main article:South Yuba River

The 65.3-mile-long (105.1 km)[2]South Yuba River originates at Lake Angela inNevada Countyabout three quarters of a mile north ofDonner Pass,about three miles east of the town ofSoda Springs.After passing through Lake Van Norden with Upper Castle Creek (longer than the Lake Angela stem) entering from the right, it gathers numerous snow-fed tributaries running west through a marshy, lake-filled valley, crossingInterstate 80several times. The river briefly entersPlacer Countybefore flowing back north into Nevada County, then flows intoLake Spaulding,where much of its water is diverted south to theBear Riverdrainage. The remainder of the river turns northward into a gorge nearEmigrant Gapbefore continuing west. It receives Canyon Creek from the right, then receives Poorman Creek also from the right nearWashington.The river continues west into the foothills and intoSouth Yuba River State Parkwhere it is bridged by State Route 49. It joins the Yuba River at the upper end ofEnglebright Lake.[8]

Main stem

From the joining of the North Yuba River and Middle Yuba River, the Yuba River mainstem flows southwards, then southwest, through the Sierra Nevada foothills, forming the Yuba-Nevada County border. The river widens into upper Englebright Lake near French Bar, and is joined by the South Yuba within the reservoir. It passes through theEnglebright DamnearLake Wildwoodand is then joined by Deer Creek (which flows out of Lake Wildwood) on the left. The Yuba River bed widens considerably as it flows out into theSacramento Valleynear theYuba Goldfields,a section of the Yuba River valley consisting of dredged sediments washed down byhydraulic miningin the 19th century. The river then turns southwest, flowing through irrigated farmland. It then skirts the south side ofMarysvilleand empties into the Feather River between the cities of Marysville,Yuba CityandLinda.[8]

History

[edit]

The Yuba River valley was originally one of the most densely populatedNative Americanareas in California. Historians divide indigenous peoples living in the Yuba River area into several groups – theKonkow,Maidu,NisenanandMiwok.[9][10]These groups did not function as large tribes; rather, they were divided into hundreds of small villages, with distinct governments but similar customs. Like other indigenous people of the Sierra Nevada foothill region, their staple food wasacorns,but they also hunted and gathered for other foods including abundant salmon runs in the Yuba River.[11]

In the 1850s, theCalifornia Gold Rushbrought large numbers of European-American settlers into the area, followed by many Mexican, African and Chinese immigrants. These settlers brought diseases with them, to which the Native Americans had no immunity. Within a few years, these diseases wiped out most of the native population. The Yuba River and its forks were one of the richest parts of theMother Lode,and miners poured to the region in great numbers.[12]Although gold was first extracted by simple methods such as panning and sluicing, large-scale industrialhydraulic miningleft a much greater impact. About 25 million cubic yards (19,400,000 m3) of hydraulic mining debris was carried down the Yuba River. This raised stream beds up to 50 ft (15 m) in places, buried riverside land under sediment, and increased the risk of flooding.[13]The practice was banned in 1884 following lawsuits from farmers who had been affected by the debris flows.

Much of the debris left by the destruction of hydraulic mining remains today as theYuba Goldfields.[14][15]In addition, the extensive use ofmercuryin processing gold led to contamination of a relatively large area. The contamination was still detectable in 2013 and will be so for an estimated time of more than 10,000 years.[16]

In 1877, the world'sfirst long-distance telephone linewas strung along the South Yuba River fromFrench Corralto French Lake (now calledBowman Lake), a distance of 58 miles (93 km).[17]

Dams and diversions

[edit]
Yuba River at Parks Bar, 1991

Like the majority of California rivers, the Yuba was dammed at many points during the 20th century, and large amounts of water are withdrawn for irrigation and municipal water supply.Daguerre Point Damwas built in 1906 by theU.S. Army Corps of Engineersin order to trap hydraulic mining debris. After concerns about its impact on fish populations, the dam was fitted withfish laddersin 1937.[18]In 1922-24PG&Ebuilt the original Bullards Bar Dam to producehydroelectricityand trap debris. The concrete archEnglebright Damwas built in 1941 to trap mining debris following the re-legalization of hydraulic mining during the 1930s. However, mining never resumed on a Gold Rush scale in the Yuba River watershed. Today, Englebright serves mainly to producehydroelectricity.[19]

New Bullards Bar Damwas built on the North Yuba River in response to the huge flood of December 1955,[20]which destroyed much of Yuba City.[21]Completed in 1969, the 645 ft (197 m) high concrete arch dam is one of the tallest dams in the United States, replacing and submerging the old Bullards Bar Dam. It stores almost 1 million acre feet (1.2 km3) to provide flood control, irrigation and hydroelectricity.[22]

The Yuba River Development Project includes New Bullards Bar Dam and a number of supporting facilities, including a diversion dam (Our House Dam) and tunnel which divert the Middle Yuba River into New Bullards Bar Reservoir, to increase hydropower generation. The 340megawattNew Colgate Powerhouse is located about 4 miles (6.4 km) below New Bullards Bar Dam, and it generates over 1.3 billionkilowatt hoursof energy per year.[23][24]These diversions have resulted in the seasonal dewatering of the lower North Yuba River and Middle Yuba River and about four miles of the main Yuba River.

The Middle Yuba River and South Yuba River are linked by theYuba-BearandDrum-Spauldinghydroelectric projects, which are owned by theNevada Irrigation Districtand PG&E, respectively. These two interconnected projects generate a combined 1.2 billion kilowatt hours per year[25]and with over 40 dams and reservoirs and 16 powerhouses, are considered the most complex hydroelectric scheme in the United States.[26]Major dams includeJackson Meadows DamandBowman Dam(part of Yuba-Bear) andLake Spaulding DamandFordyce Lake Dam(part of Drum-Spaulding). These projects divert a portion of the Yuba River's flow to theBear River,a tributary of the Feather River further south.

Other dams include Scotts Flat and Wildwood on Deer Creek; and Mildred and Virginia Ranch on Dry Creek, a lower tributary of the Yuba.

Environmental issues

[edit]

TheCalifornia Office of Environmental Health Hazard Assessmenthas issued a safe eating advisory for any fish caught in Yuba River, North Yuba River, and Middle Yuba River due to elevated levels of mercury.[27]

The Spring and Shady tributaries of the South Yuba[28]contain dozens of historic mine locations, the largest of which is the San Juan Ridge Mine. Mining operations in the area began in 1850 and have been more or less driven by the price of gold since that time.[28]In 1995, the San Juan Ridge Mine Corporation stopped gold mining operations following the breach of an underground aquifer that caused flooding and the overflow of containment ponds.[28]This breach released millions of gallons of mine waste into Spring and Shady creeks, drained and contaminated 12 local wells through the oxidation of naturally occurring heavy metals- including a well that supplied drinking water to a local K-8 school.[28]The mining company proposed to re-open their mine for gold extraction in 2012, which would require pumping up to 3.5 million gallons of groundwater to operate each day.[28]Pumping groundwater at this scale would likely deplete the underground aquifer that provides water to hundreds of community members. This could potentially cause serious impacts to surface water quality in Spring and Shady creeks due to increased surface flows from mining practices.
