SACRAMENTO, a river of the United States of North America, in California, rises in a chain of mountains connecting the Sierra Nevada with the coast range, and flows generally southwards, uniting with the San Joaquin from the south, at the head of Suisoon Bay, through which their united waters are discharged into the Pacific. Its whole length is about 370 miles, for 200 of which it is navigable. It abounds in fish, the catching of which is here an important branch of industry. The valley watered by the Sacramento is one of the most beautiful and fertile portions of California.
