Hetch Hetchy Reservoir

Hetch Hetchy Reservoir is a large water storage facility located in Yosemite National Park, California. Built in the early 20th century, it was created to supply water and hydroelectric power to San Francisco and its surrounding areas. The reservoir fills with water from the Tuolumne River, and its construction prompted significant debate, as it flooded a beautiful valley similar to Yosemite Valley, sparking discussions about conservation versus development. Today, it remains a crucial water source while also highlighting the balance between natural preservation and urban infrastructure needs.
