What fish are in the Napa River?
The river also supports a remarkable diversity of fishes and recovering salmonid populations, especially chinook salmon ( Oncorhynchus tshawytscha) and steelhead trout ( Oncorhynchus mykiss ). In 2003 the Napa County Resource Conservation District began an ongoing salmon monitoring program, and have recorded a run of approximately 400 - 1000 fall-run Chinook salmon the past several years. The Chinook run begins in late October through January. Conclusive evidence of historical chinook salmon populations in the Napa River basin have not been established, but the river provides appropriate habitat for salmon and its location near the entrance to the Sacramento / San Joaquin Rivers make it likely that salmon would have at least ventured into the Napa River. In 2013, a genetics study of Napa River chinook salmon revealed that two adults migrated from the Klamath River and successfully spawned in the Napa River, since four juvenile chinook collected from the Napa River in 2010 were proved to be siblings from the close similarity of their DNA and that the latter was characteristic of Klamath River chinook. These findings have important implications for the protection of the federally endangered Coastal California Chinook Salmon ESU since the Napa River, nor any stream in the Bay Area, was included in this ESU.

Where does the San Joaquin River flow?
The majority of the river flows through quiet agricultural bottom lands , and as a result its meandering course manages to avoid most of the urban areas and cities in the San Joaquin Valley. About 11 mi (18 km) west of Modesto, the San Joaquin meets its largest tributary, the Tuolumne.
How much water does the San Joaquin River have?
The natural annual discharge of the San Joaquin before agricultural development is believed to have been between 6–7.9 million acre feet (7.4–9.7 million dam 3 ), equaling a flow of roughly 8,300 to 10,900 cu ft/s (240 to 310 m 3 /s). Some early estimates even range as high as 14 million acre-feet (17.3 million dam 3 ), or more than 19,300 cu ft/s (550 m 3 /s). The numerous tributaries of the San Joaquin – the Fresno, Chowchilla, Merced, Tuolumne, Mariposa Creek, Calaveras, Mokelumne, and others – flowed freely across alluvial flood plains to join the river. All of the major tributaries of the river originate in the Sierra Nevada; most of the streams that start in the Coast Range are intermittent, and contribute little to the flow of the San Joaquin. During the winter, spring, and early summer, storms and snowmelt swell the river; in 1914 – before the development of major dams and irrigation diversions – the California Department of Engineering estimated the river's flow in full flood at 325,000 cu ft/s (9,200 m 3 /s). In late summer and autumn, there is little water left over to replenish stream flow. Historically, groundwater seepage from Tulare Lake maintained a significant base flow in the river during the dry months – some accounts suggest over 50 percent.

How long has the San Joaquin Valley been inhabited?
People have inhabited the San Joaquin Valley for more than 8,000 years, and it was long one of the major population centers of pre-Columbian California. Starting in the late 18th century, successive waves of explorers then settlers, mainly Spanish and American, emigrated to the San Joaquin basin, first exploiting then driving out the indigenous tribes. The newcomers quickly appropriated the rich natural and hydrologic resources of the watershed for use in farms and cities, but found themselves plagued by flood and drought. Because of the uniform topography of the San Joaquin Valley, floods once transformed much of the lower river into a huge inland sea .
What is the longest river in California?
The San Joaquin River ( / ˌsæn hwɑːˈkiːn /; Spanish: Río San Joaquín) is the longest river of Central California. The 366-mile (589 km) long river starts in the high Sierra Nevada, and flows through the rich agricultural region of the northern San Joaquin Valley before reaching Suisun Bay, San Francisco Bay, and the Pacific Ocean.

Overview
Course
The river's source is located in the Ansel Adams Wilderness, in the south-central Sierra Nevada at the confluence of three major affluents: the Middle Fork, which rises from Thousand Island Lake at almost 10,000 ft (3,000 m) above sea level, meets the North Fork, which starts 1.8 mi (2.9 km) southeast of Mount Lyell, and the South Fork, which begins at Martha Lake in Kings Canyon National Park and …
Name
The river was called many different names; at times different parts of the river were known by different names. The present name of the river dates to 1805–1808, when Spanish explorer Gabriel Moraga was surveying east from Mission San José in order to find possible sites for a mission. Moraga named a tributary of the river (it is not known which one) for Saint Joachim, husband of Saint Anne and father of Mary, the mother of Jesus. The name Moraga chose was later applied t…
Geology
In a geologic context, the San Joaquin River can be divided into two major segments. The upper 97 mi (156 km) above Friant Dam in the Sierra is characterized as a steep-gradient, rocky mountain stream. Over millions of years, the upper San Joaquin, as well as the upper reaches of most of its tributaries, have eroded enormous amounts of rock and sediment from the mo…
History

Restoration
As part of urban renewal in the 1970s, a concrete cover was removed from culverted sections of the Napa Creek, re-exposing the water to daylight. There is some debate as to whether this constituted one of the country's earliest "daylighting" projects, since the construction was undertaken with little thought to the river's ecology or restoration of riparian habitat. This construction is not believed to be responsible for later flooding along the river.
Napa Flood of 1986
In 1986, the worst of 23 floods recorded since 1865 on the Napa River occurred. 5,000 people were evacuated, 250 homes were destroyed, and three people lost their lives.
After the devastating flood of 1986, the dormant Napa River Flood Project was revitalized. The Project underwent a lengthy redesign and was approved by the local voters in 1998. Construction began in 2000 and was completed by 2015.
