About Us

The Mid-Pacific Region is one of five Reclamation Regions that carry on day-to-day planning, management, and operational activities. 

The Region encompasses all the lands drained by rivers flowing into the Pacific Ocean along the coast of California north of the Tehachapi Mountains and all the lands drained by rivers that both begin and end in Nevada. 

The Region also includes the area in southern Oregon drained by the Klamath River.  In general, the Region covers the northern two-thirds of California, most of western Nevada, and a part of southern Oregon.

The Region’s goal is to balance many competing and often conflicting needs among numerous water uses and users.  These include urban and industrial use, agriculture, fish and wildlife habitat, water quality, wetlands, endangered species issues, Native American Tribal Trust issues, power generation, and recreation. 

The Region strives to develop and implement a balanced approach to water allocation, serving users while protecting the environment.

The Mid-Pacific Region is best known for the massive Central Valley Project (CVP) built to tame the flood waters and irrigate the semi-arid acreage of California’s vast Central Valley, the CVP grew over the last 50 years to become one of the largest water storage and transport systems in the world.

The CVP is a system of 20 reservoirs and more than 500 miles of major canals and aqueducts that encompasses 35 counties.  The CVP has a combined storage capacity of more than 11 million acre-feet of water, manages approximately 9 million acre-feet of water, and delivers more than 7 million acre-feet in a year more than any other single California agency in a normal year. 

There are 11 hydroelectric powerplants providing an average of 5.5 billion kilowatt hours of electricity to supply around 1.5 million people with power throughout the Mid-Pacific Region.
