  • Drought Background

    Lake Shasta Drought

    California is experiencing its most severe drought in recent history. Lake Shasta is currently at 31% of its total capacity. Learn more about the current water conditions in California and the Bureau of Reclamation's webpage.

  • Where Our Water Comes From

    The Central Valley Project Improvement Act (CVPIA) provides for a water supply for some refuges similar to Central Valley Project (CVP) senior water right holders. The CVPIA was enacted to mitigate for damage done to wildlife habitat by the CVP, in part by providing water to California's remnant wetlands on some refuges in the Central Valley.

  • Impacts on Refuges

    Sac 75 Water Distribution Map

    In 2014, the Sacramento, Delevan, and Colusa NWRs will be receiving only 75% of their allocated water. In accordance with the Complex's Comprehensive Conservation Plan (CCP) and other management documents (see below), the refuge managers and biologists continue to strategize for the optimal use of water to continue to meet the refuges' conservation goals. The staff is being flexible with water usage so water conserved early in the season can be used later in the season to support migratory bird populations and meet management objectives to the extent possible. State and federal land managers are working strategically together on a landscape-wide level in their water management.

  • Impacts on Wildlife and Habitat

    The National Wildlife Refuges in California compensate for the loss of ~95% of the Central Valley's historic wetland habitat. Recent midwinter counts have shown that 5-6 million ducks and geese winter in the Central Valley. This accounts for ~60% of wintering waterfowl in the Pacific Flyway. The mosaic of managed wetlands and winter-flooded rice fields (mostly on private lands) in the northern Sacramento Valley support 4-5 million waterfowl or 50% of the wintering waterfowl in the Pacific Flyway.
