In 2014-15 season, the Sacramento, Delevan, and Colusa NWRs received only 75% of their allocated water. The rain in November and December 2014 brought the water levels up to 100%. 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.
