The San Joaquin River is a vital waterway located in the state of California, United States. It is approximately 366 miles (589 kilometers) long and drains an area of around 15,600 square miles (40,400 square kilometers). The river originates in the Sierra Nevada mountain range and flows southwest through the San Joaquin Valley, eventually emptying into the Sacramento-San Joaquin River Delta.
Geography and Course
The San Joaquin River begins at the confluence of three forks: the Middle Fork, the North Fork, and the South Fork. The Middle Fork is the longest of the three, stretching for about 35 miles (56 kilometers) from its source at Thousand Island Lake. The North Fork is approximately 25 miles (40 kilometers) long, while the South Fork is around 20 miles (32 kilometers) long. From its origin, the San Joaquin River flows through the Sierra National Forest, the Stanislaus National Forest, and the San Joaquin Valley, passing through several cities, including Fresno and Stockton.
Key Features and Tributaries
Some of the key features of the San Joaquin River include its numerous tributaries, such as the Merced River, the Tuolumne River, and the Stanislaus River. These tributaries contribute significantly to the river’s water flow and support a diverse range of aquatic life. The San Joaquin River also features several notable landmarks, including the San Joaquin River Gorge and the Mendota Pool.
