Flows will depend on whether the year is wet, dry or for intermediate levels of precipitation. [38][39] Another narrative does not mention Fages' name, but does say that Crespí was the one who reached Suisun Bay in 1772. [98], Even with the presence of Friant and numerous other flood control dams, large floods still caused significant damage along the San Joaquin River all the way through the late 1950s. san Francisco estuary & watershed science 2 SUggESTED CITATIoN Kimmerer, Wim J.; Matthew L. Nobriga. In fact, despite the relatively small percentage of developed areas, more than 50% of the population lives in the watershed's four largest cities: Fresno, Bakersfield, Stockton and Modesto.[169]. [105] The new reservoir would flood 15 mi (24 km) of the San Joaquin River including whitewater runs, fishing areas and historic sites. The San Francisco Bay watershed covers 4600 square miles, of which the Bay encompasses 1600 square miles. The maximum drop in elevation was near Mendota, the northward bend of the San Joaquin River, at over 28 feet (8.5 m). The sloping alluvial fan of the Kings River divides the northern San Joaquin Valley from the Tulare Basin. In 1931 California's Department of Water Resources came up with the State Water Plan, which entailed the construction of dams and canals to transport water from the Sacramento River to the rapidly dwindling San Joaquin. The Bureau of Reclamation in conjunction with the California Department of Water Resources has proposed the construction of a new dam on the San Joaquin, Temperance Flat Dam, a few miles upstream of Friant. As of 2011[update], plans had been finalized for a $14.5 million hatchery near Friant Dam as part of a $20 million federal restoration project for the fish. Dams. If combined with the 16,200 sq mi (42,000 km ) Tulare Basin, which historically (and still rarely) experiences northerly outflow to the San Joaquin River, it would be the largest single drainage basin entirely in the state. [67], One of the most powerful early irrigation empires was the Kern County Land and Water Company, established in 1873 by land speculator James Ben Ali Haggin, which grew to supply over 400,000 acres (160,000 ha) through their canal system. Downstream portions of the river's main tributaries were populated mainly by largemouth and smallmouth bass, redear sunfish and white catfish, while native species have survived relatively well in the upper reaches of the river and its tributaries, which also play host to introduced brown trout. Where these two large rivers meet near Sacramento, a great inland Delta is formed where the river waters collect before passing through the Carquinez Strait into San Francisco Bay. This may happen in 2016 or 2017. It is widely believed that the dominant grass species throughout the San Joaquin River valley and Tulare Basin, as well as the Sacramento Valley, the Sierra foothills and Coast Ranges, was Nassella pulchra, a type of bunchgrass more commonly known as purple needlegrass. [17][58], The real influx came in 1848, when a gold strike on the American set off the California Gold Rush. [167] In Madera County, near the geographic middle of the basin, growth was 51.5% between 1990 and 2003, the highest in the San Joaquin basin. At 31,800 sq mi (82,000 km2), the San Joaquin watershed drains a fair swath of inland central California, covering an area nearly the expanse of South Carolina. For thousands of years, the Sacramento-San Joaquin River Delta (Delta) was a vast plain with seasonal flooding, creating 1000 square miles of brackish tidal marsh, narrow, branching tidal channels, and freshwater marshes. Seven major tributaries flow directly into the San Joaquin River, all of which run from the Sierra Nevada westwards into the main stem. The Sacramento/San Joaquin Literary Watershed Project is an attempt to comprehensively document the literary landscape of this region, delineated in a broad sense by the combined watershed of the Sacramento and San Joaquin Rivers and their tributaries. Drought Water Right Allocation Tool Applied to the San Joaquin River Basin By WESLEY WALKER B.S. Find your Watershed Area. Additional rehabilitation work is projected to continue until 2016 to ensure that the river can transport 4,500 cu ft/s (130 m3/s) of water through rainfall and releases from Friant Dam all the way to Bear Creek and the Eastside bypass. The Merced River watershed encompasses 1,726 square miles (4,470 km 2) in the central Sierra Nevada. Many of these people settled in the San Joaquin Valley, most in the existing towns such as Stockton, Fresno and Bakersfield but some establishing new settlements. The water is largely held behind Friant Dam. The watershed study area of this thesis focuses on the San Joaquin River watershed and includes the non-agricultural Sierra Nevada mountainous region. [54], In the early 1830s, a few fur trappers from the Pacific Northwest exploring southwards into the San Joaquin Valley arrived just in time to be greeted with a sight of horror. During Mexican rule, the mission lands in the San Joaquin Valley were subdivided to wealthy landowners (rancheros) and caused even more conflicts between the Mexicans and the Native Americans. The watershed is bordered on the east, north, and west by mountains including the Sierra Nevada, Cascade, and Coast Ranges. Despite the enormous price tag of at least $2.6 billion, according to the U.S. Bureau of Reclamation for its preferred alternative, the dam would only yield 70,000 acre-feet of water per year on average. By: Lisa B. Hanf. [44] The group skirted the western foothills of the Sierra and christened many place names that remain in use today. Download KML Version. These engineering works changed the fluctuating nature of the river forever, and cut off the Tulare Basin from the rest of the San Joaquin watershed. We are a Water Quality Coalition formed by farmers in San Joaquin County, Contra Cost County and Calaveras County to monitor surface and groundwater quality and help farmers meet the requirements of the Irrigated Lands Regulatory Program. Most of the Sierras are underlain by granitic igneous and metamorphic rock dating back to the Mesozoic Era (250-66 MYA); in addition many of the San Joaquin's tributaries flow across a foothills region of metamorphosed volcanic rock more famously known as the Mother Lode Gold Belt. Contact Us to ask a question, provide feedback, or report a problem. Major rivers in the Tulare Lake Basin come out of the Sierra Nevada Mountains and include the Kings, Kaweah, Tule, and Kern Rivers. Green Sturgeon, a more marine species, migrates in spring to spawn in the headwaters of the Sacramento River before returning to the estuary during the fall. The San Joaquin River (/ˌsæn hwɑːˈkiːn/; Spanish: Río San Joaquín) is the longest river of Central California in the United States. The latter sends water into the Tulare Basin through the natural channel of the slough, which in essence conveys water in either direction depending on the time of year – north into the San Joaquin during the rainy season, south into the Tulare during the dry months. 5, San Joaquin River National Wildlife Refuge, "Boundary Descriptions and Names of Regions, Subregions, Accounting Units and Cataloging Units", "Restoring the San Joaquin River: Following an 18-year legal battle, a great California river once given up for dead is on the verge of a comeback", "Historic Conditions in the San Joaquin River Watershed", "Water-Year Summary for Site USGS 11251000", "Sacramento-San Joaquin River Basin Study", "USGS #11303500 on the San Joaquin River near Vernalis, CA: Annual Water-Data Report", "USGS Gage #11303500 on the San Joaquin River near Vernalis, CA (Monthly Statistics)", "Geologic Context and History of the San Joaquin River", "Compressional uplift in the central California Coast Ranges", "The United States Geological Survey Releases Central Valley Groundwater Report", "Bakersfield Archaeological/Cultural General Information", "Paleoclimate History of Tulare Lake, California", "Native Occupation of the Terminus Reservoir Region", "Chapter 9: Historic and Cultural Resources", "Last blast from steamers on the San Joaquin", "When great steamboats plied our rivers and bay", "Merced River Water Temperature Feasibility Investigation Reconnaissance Report", "San Joaquin River flowing through dry stretches", "Schematic Profile of the Big Creek System", "Case #3: Crane Valley Hydroelectric Relicensing Project – Madera County, Ca", "Central Valley Project: Project History", "Second Victory Over Friant Dam and Restoration of the San Joaquin River", "Mendota Dam, the Delta-Mendota Canal, and Mendota Pool", "San Joaquin River Restoration Program and Flood Management Coordination", "State Plan of Flood Control Descriptive Document (Chapter 3)", "Temperance Flat Frequently Asked Questions", "Temperance Flat reservoir closer to reality: State water bond would benefit Valley projects", "Is Temperance Flat Dam Proposal Down to Its Last Strike? Rather than cut back on groundwater use, the southern San Joaquin Valley interests are proposing the San Joaquin Valley Blueprint: build the Temperance Flat Dam, expand water storage at San Luis Reservoir and build two new nearby reservoirs, and enlarge and build canals from the state and federal aqueducts on the west side of the Valley to the Valley’s east side— and expand pumping from the beleaguered … The Merced River is the second largest by length and drainage basin, but the Mokelumne River has a greater flow. 209-851-4204. [131], Introduction of predatory fish species such as bluegill and various types of bass that prey on salmon smolt are also a major contributor to the decline. [160][161], The overwhelming majority of the economic base in the San Joaquin River watershed is provided by agriculture. Although some of his men confirmed it, Smith did not make any mention of the precious metal in his journal. During that year, Huntington and Eastwood devised plans to utilize the water of the San Joaquin River and some of its headwaters tributaries in what would become one of the most extensive hydroelectric systems in the world, known as the Big Creek Hydroelectric Project. Without recruitment, high flow releases scour gravel from spawning beds, so that they gradually become smaller and smaller. On the south, the Tehachapis wall off the Tulare Basin from the Mojave Desert. [158], The San Joaquin Valley's major southeast-northwest axis runs roughly parallel with the Pacific coast of California; it measures 280 by 115 mi (451 by 185 km) covering all or parts of seventeen California counties[n 2] stretching from north of Lodi to well south of Bakersfield. The best temperatures for spring and fall run Chinook salmon are between 42 °F and 57 °F. It also contains the only inland delta in the world. In 1925 the city put forth a $1.3 million bond for dredging the lower San Joaquin from its mouth to the Port of Stockton – a distance of 41 mi (66 km) by river. [107][104][108][109], However, opponents assert that the upper San Joaquin River, which is already controlled by dozens of smaller reservoirs upstream of Millerton Lake, will not provide sufficient discharge to fill the reservoir except in very wet years. Climate. Tributaries are listed below proceeding from the mouth upstream, with their respective main-stem length, watershed and discharge noted. The Coast Ranges bound the watershed on the west and borders on the drainages of the Pajaro River, Salinas River and the endorheic Carrizo Plain.

The San Joaquin Basin has mild winters and particularly hot and dry summers. [36] Many of the surviving examples of acorn milling areas can still be found in the foothills, especially around the Kaweah River area. During these pre-European times, the San Joaquin River flowed through rich grasslands and sprawling marshes, flooding every few years and transforming much of the valley into lakes. [40], In the autumn of 1772 Fages set out from Mission San Luis Obispo de Tolosa in pursuit of deserters from the Spanish army, and traveled east then north over the Tehachapi Mountains through Tejón Pass, which today carries Interstate 5 into the San Joaquin valley. [117] Some of the richest remaining marsh habitats are in the Sacramento-San Joaquin Delta, which despite significant agricultural and infrastructure development, has retained many of its original swamps and backwaters. [17] Such conflict created enormous cultural loss, and violence continually escalated between the two sides, with no apparent end in sight. [6] In late summer and autumn, there is little water left over to replenish stream flow. The San Joaquin watershed in the California's Central Valley was selected as the study area . The Calaveras River watershed is located in northern California in Calaveras, Stanislaus, and San Joaquin counties. Tributary rivers that flow into the San Joaquin River include (from south to north) the Fresno, Chowchilla, Merced, Tuolumne, Stanislaus, Calaveras, Mokelumne, and Cosumnes Rivers. [162] The main crop in the valley by annual sales is cotton, but more than 200 types of produce are grown along the San Joaquin River and in the Tulare Basin, including rice, almonds and lettuce. Larger flows in the fall may make it possible for the river to extend further towards the ocean, but for the last several years, this is a rare occurrence. Today there are approximately 1,100 miles of levees in the Delta protecting 625 square miles of productive agricultural areas and 500,000 residents in small, rural communities and urban areas. The watershed approach facilitates participation from interested stakeholders, optimizes use of environmental laws, and fosters local stewardship necessary to generate and sustain water quality improvements. [93] The diversion of water off the San Joaquin at Friant Dam leaves little more than a trickle below the dam in most years, except for releases serving farms in the immediate area downstream of Friant. Additional deepening work was carried out in 1968 and 1982. EPA addresses water pollution from the watershed approach, a comprehensive framework for addressing water resource challenges. [88], As early as the 1870s, state and federal agencies were already looking at the Central Valley as an area in need of a large water transport project. California’s primary hydrologic system, the San Francisco estuary and its upstream watershed, is vulnerable to the regional hydrologic consequences of projected global climate change. Streamflow information and snowpack data for the Middle San Joaquin-Lower Watershed featuring river levels and total snow accumulations for hydrological unit code 18040002. The San Joaquin series consists of moderately deep to a duripan, well and moderately well drained soils that formed in alluvium derived from mixed but dominantly granitic rock sources. [3], Below Friant Dam (RM267), the San Joaquin flows west-southwest out into the San Joaquin Valley – the southern part of the Great Central Valley – passing north of Fresno. The San Joaquin River watershed is bordered on the east by the Sierra Nevada Mountains and on the west by the Coast Range mountains. It is also hoped that the water will help dilute contaminants in the river caused by pesticides and fertilizers that are applied to the surrounding farmland. [166] The largest cities are Bakersfield, near the south end of the valley on the Kern River; Fresno, roughly in the geographic center; Modesto, on the Tuolumne River; and Stockton, on the southeast fringe of the Delta region. Second Edition. The present conditions of the San Joaquin River at Friant Dam, the average discharge was 324 cu ft/s (9.2 m3/s), or 0.234 million acre-feet per year. As early as the 1807 Moraga expedition, it was reported that some natives were hostile and attempting to steal their horses. [66] The vulnerability of the small local infrastructure led to the establishment of irrigation districts, which were formed to construct and maintain canals in certain areas of the valley. Major Cities. [75] It has been said that fights over the river have caused "some of the most bitter and longest running lawsuits ever to clog the courts. There have been seepage concerns below this part of the river, so current flows are restricted below the Sack Dam. By reconnecting, it means the portion from Friant Dam to where the San Joaquin River joins the Merced river above Vernalis. This is believed to be a result of the combination of the abrupt geometry change from the shallow river upstream of Stockton to the deep water channel, in addition to pollution from the harbor and city and poor tidal mixing. San Joaquin County Open Space and Farmland Trust c/o Mike Robinson 7000 S. Inland Drive In 1983, the 155 MW Kerckhoff No. These included San Joaquin City, near the confluence of the San Joaquin with the Stanislaus, probably the largest of these post-gold-rush boomtowns. [163] The crops grown in these four counties alone are valued at over $12.6 billion annually,[163] while the production of the entire valley is estimated at more than $14.4 billion. The watershed study area of this thesis focuses on the San Joaquin River watershed and includes the non-agricultural Sierra Nevada mountainous region. Historically, surface water was able to provide all the needed supply, but as agricultural lands spread across more and more of the valley, groundwater pumping became increasingly common. Rivers that drain the Tulare Basin do not have a natural surface water pathway out of the watershed. [147], Phase One improvements include the following: The San Joaquin River east of Los Banos will be increased to route up to 475 cu ft/s (13.5 m3/s) of water by December 2011. [53] It is still disputed over whether Smith's party discovered gold on the San Joaquin or one of its tributaries. San Joaquin, Stanislaus, Tuolumne, and Merced Rivers, and the southern part of the Delta. The San Joaquin River basin is roughly synonymous with the San Joaquin Valley, and is bounded by the Sierra N… [71], Miller and Lux were not any newer to the San Joaquin Valley than had been Haggin, but were the driving influence on valley agribusiness until well into the early 20th century. A fish ladder will also be added to the Sack Dam.[149][150][151]. Prior to 19th century European settlement and 20th century water development, Tulare Lake Basin was characterized by four large lakes (about 800 square miles in wet years) and large tracts of wetlands (about 625 square miles) that periodically drained into the San Joaquin River watershed. Land Use. The name Moraga chose was later applied to the entire river; it was in common use by 1810. The Delta Mendota Canal was constructed to replenish water in the San Joaquin River by transporting Sacramento River water to Mendota Pool where it is directed to the San Joaquin River channel and agricultural users. Historically, San Francisco Bay had about 300 square miles of tidal marsh with 6000 miles of channels and 12 square miles of shallow pan. Middle San Joaquin-Lower Watershed Hydrologic Unit Code 18040002. The river typically ends above the Mendota Pool. It has a Mediterranean climate with hot, dry summers and cool, wet winters. As said by Tom Mott, the son of Miller and Lux' irrigation superintendent, "Miller realized you couldn't do anything with the land unless you had the water to go with it. Established in 1851, the town maintained considerable size until 1880, when trade competition from nearby Stockton caused it to diminish. “From a precedent standpoint, the Creek Fire is huge. [48], However, the greater military power of the Europeans resulted in the indigenous people getting pushed further and further back from their native lands; this did not change when California became part of Mexico in 1821, despite the fact that the new government secularized the Spanish missions and as a result freed many enslaved indigenous people. , watershed and the southern part of the River was last connected to the between.
