Mid-Pacific Region Organization

Bureau of Reclamation

President Theodore Roosevelt signed the Reclamation Act in 1902, creating the agency that would become the Bureau of Reclamation. The agency’s initial mission: Develop and provide water for the 17 arid western states. Reclamation has built 475 major structures, including Hoover Dam on the Colorado River and Shasta Dam on the Sacramento River.

Mid-Pacific Region

The Mid-Pacific Region is one of five Reclamation regions. The Region covers the northern two-thirds of California, most of western Nevada and part of southern Oregon. The Region places great importance on fulfilling its obligations for water delivery, water conservation, water recycling and reuse, power generation, and protecting natural and cultural resources. The Region develops partnerships with customers, states, and Native American Tribes; and brings together a variety of interests to address competing needs for limited water resources.
