New Don Pedro Dam, Earth and rockfill dam in Tuolumne County, United States
The New Don Pedro Dam extends 1,900 feet across the Tuolumne River, reaching a height of 580 feet to create a reservoir with 160 miles of shoreline.
Construction of the dam started in 1967 to replace the original 1923 structure, marking a significant upgrade in water management capabilities for California's central valley.
The dam received its name from Pierre Sainsevain, a French prospector known as Don Pedro, who established a mining settlement near the original dam location.
The hydroelectric facility generates 203 megawatts of power through four generators while providing irrigation water to agricultural districts in Modesto and Turlock.
The reservoir contains the submerged remains of the original Don Pedro Dam, which was the highest dam in the world when completed in 1923.
