Sacramento, the largest river of California, rises in the northeastern part of the state, and flows southwest through the Sierra Nevada to Shasta, south to Sacramento and thence southwest into Suisun Bay, through which its waters pass into San Pablo Bay and to the Pacific. It is about 500 miles long, and is navigable for small boats to Red Bluff, nearly 250 miles. Its chief branch is the San Joaquin.
