Frequently Asked Questions
What is the main use of the San Joaquin River’s water?
The primary use of the San Joaquin River’s water is for agricultural irrigation in the San Joaquin Valley, supporting a wide range of crops that contribute significantly to California’s economy.
Which major reservoir is located on the San Joaquin River?

Where does the San Joaquin River eventually flow?
The San Joaquin River flows northward through the San Joaquin Valley and eventually converges with the Sacramento River to form the Sacramento-San Joaquin Delta, which then drains into the San Francisco Bay.
What is soil salinization in the San Joaquin Valley?
Soil salinization is the accumulation of salts in the soil, a common issue in arid agricultural regions like the San Joaquin Valley due to extensive irrigation and poor drainage. It can reduce crop yields and damage soil structure.
What is the Central Valley Project’s role concerning the San Joaquin River?
The Central Valley Project (CVP) is a federal water management and hydroelectric power generation project. It includes infrastructure on the San Joaquin River, such as Friant Dam and canals, to store and deliver water for irrigation, municipal use, and environmental purposes.
