As of June, 2015, the Sacramento, Delevan, and Colusa NWRs will receive 75% of their 2015-2016 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.
