Which dam is located on the Stanislaus River?

The New Melones Dam is located on the Stanislaus River, primarily in Calaveras County, California. This embankment dam was built for various purposes including water storage, flood control, hydroelectric power generation, and recreation. It plays a crucial role in the Central Valley Project, which supplies agricultural and municipal water to the region.

The other dams listed serve different rivers or systems. Hetch Hetchy Dam is situated on the Tuolumne River, Shasta Dam is on the Sacramento River, and Oroville Dam is located on the Feather River. Each of these dams supports various water management and power generation efforts but is not related to the Stanislaus River as the New Melones Dam is.
