The Sacramento River is the longest river entirely within the U.S. state of California. Starting at the confluence of the South Fork and Middle Fork Sacramento River, near Mount Shasta in the Cascade Range, the Sacramento flows south for , through the northern Central Valley of California, between the Pacific Coast Range and the Sierra Nevada.
Not far downstream from its confluence with the American River, the Sacramento River joins the San Joaquin River in the Sacramento River Delta, which empties into Suisun Bay, the northern arm of San Francisco Bay.
The chief tributaries of the Sacramento River are the Pit, Feather, McCloud and American rivers. The Pit River is the longest of these, but the Feather and American rivers carry larger volumes of water. The Pit River's watershed formerly included Goose Lake, and still does during rare periods of high water.
CourseAccording to Mt. Shasta Recreation & Parks District, the designated headwaters of the Sacramento River are at about 3600 feet (1100 m) elevation in Mount Shasta City Park . The USGS cites the river's source as the confluence of the South Fork Sacramento River and Middle Fork Sacramento River.prings feeds Big Springs Creek which flows south into Lake Siskiyou. However, feeding Lake Siskiyou from the west are the North, Middle, and South Forks of the Sacramento River which bring water from much higher elevations, including from Castle Lake (elevation
On May 14, 2007, two humpback whales were spotted by media and onlookers traveling the deep waters near Rio Vista. The duo, generally believed to be mother and calf (Delta, the mother and Dawn, her calf), continued to swim upstream to the deep water ship channel near West Sacramento, about inland. There was concern because the whales had been injured, perhaps by a boat's propeller or keel, leaving a gash in each whale's skin. The whales were carefully inspected by biologists and injected with antibiotics to help prevent infection. After days of efforts to lure (or frighten) the whales in the direction of the ocean, the whales eventually made their way south into San Francisco Bay, where they lingered for several days. By May 30, 2007, the cow and calf apparently slipped out unnoticed under the Golden Gate Bridge into the Pacific Ocean, likely under cover of night.
Rio Vista, California hosts an annual Bass Festival each October to celebrate the return of bass to the river.
HistoryThe Sacramento River helped form the track of a trade and travel route known as the Siskiyou Trail, which stretched from California's Central Valley to the Pacific Northwest. The Siskiyou Trail closely paralleled the Sacramento River and took advantage of the valleys and canyons carved by the river through the rugged terrain of Northern California. Based on the original footpaths of Native Americans, the Siskiyou Trail was expanded by Hudson's Bay Company trappers in the 1830s, and expanded further by California Gold Rush "Forty-Niners" in the 1850s. Today, Interstate 5 and the Union Pacific Railroad occupy the path of the ancient Siskiyou Trail.
Economy and controlMan-made channels make the river navigable for upstream of San Francisco Bay; ocean-going ships travel as far inland as the City of Sacramento.
The Sacramento Area Flood Control Agency is a Joint Powers agency tasked with keeping the Sacramento River within its banks and levees. California Governor Schwarzenegger declared a State of Emergency in February 2006 in an attempt to repair the levees, whose failure could impact the drinking water quality of two-thirds of California residents.
