The Sacramento River is an important river of Northern and Central California in the United States. The state's largest river by discharge, it rises in the Klamath Mountains and flows south for over 400 miles (640 km) before reaching Suisun Bay, an arm of San Francisco Bay, and thence the Pacific Ocean. The Sacramento drains an area of about 27,500 square miles (71,000 km2) in the northern half of the state, mostly within a region bounded by the Coast Ranges and Sierra Nevada known as the Sacramento Valley. Its extensive watershed also reaches to the volcanic plateaus of Northeastern California. Historically, its watershed has reached farther, as far north as south-central Oregon where the now, primarily, endorheic (closed) Goose Lake rarely experiences southerly outflow into the Pit River, the most northerly tributary of the Sacramento.
The Sacramento has been an important transportation route since the time of the region's first inhabitants, who settled in the river valley about 12,000 years ago. Hundreds of tribes sharing regional customs and traditions inhabited the Sacramento Valley, though they received little disturbance upon the arrival of Europeans in the 1700s. One of these early explorers, Gabriel Moraga, gave the river the Spanish name, Rio de los Sacramentos, later shortened and anglicized into Sacramento. The Sacramento's waters were once abundant in fish and other aquatic creatures, notably one of the southernmost runs of chinook salmon in North America. The original natives of the Sacramento Valley drew upon the vast natural resources of the watershed, which had one of the densest American Indian populations of California.
In the 19th century the discovery of gold in the Sierra Nevada led to an enormous population influx of American settlers. Overland trails such as the California Trail and Siskiyou Trail followed the Sacramento and other tributaries, guiding hundreds of thousands of people to the goldfields and the growing agricultural region of the Sacramento Valley. By the late part of the century, many populated communities had been established along the Sacramento River, chief of which was the booming city of Sacramento. Intensive agriculture and mining contributed to pollution in the Sacramento, and significant changes to the river's hydrology and environment.
Since the 1950s the watershed have been intensely developed for water supply and the generation of hydroelectric power. Today, large dams impound the river and almost all of its major tributaries. The Sacramento's water is used heavily for irrigation purposes and serves much of Central and Southern California through the canals of giant federal water projects. While now providing water to over half of California's population and supporting one of the most productive agricultural areas in the nation, these changes have left the Sacramento greatly modified from its natural state and have caused the decline of its once-abundant fisheries.

Famous quotes containing the word river:
“I counted two and seventy stenches,
All well defined and several stinks!
Ye Nymphs that reign oer sewers and sinks,
The river Rhine, it is well known,
Doth wash your city of Cologne;
But tell me, Nymphs! what power divine
Shall henceforth wash the river Rhine?”
—Samuel Taylor Coleridge (17721834)
