The San Joaquin River (American pronunciation: san wakeen) originates in the Sierra Nevada mountain range in eastern California and flows southwest to Fresno, where it turns west and then north. Near Antioch, the San Joaquin joins the Sacramento River Delta.

The average annual runoff of the San Joaquin River basin (including tributaries such as the Mokelumne) is 7.9 million acre-feet — quite a bit less than the Sacramento's!
