Mill Creek and Deer Creek Drought Response

On May 10, 2021, Governor Newsom declared a drought state of emergency for 41 counties, including all counties within the Sacramento-San Joaquin Delta watershed (May 2021 Proclamation). The May 2021 Proclamation directs the State Water Board, in coordination with the California Department of Fish and Wildlife (CDFW), to evaluate the minimum instream flows and other actions needed to protect salmon, steelhead, and other native fishes in critical streams. Mill Creek and Deer Creek are tributaries to the Sacramento River, located in Tehama County. Both creeks support multiple self-sustaining natural populations of anadromous salmonids, including threatened Central Valley spring-run Chinook salmon and threatened California Central Valley steelhead. Protecting and restoring these populations is recognized as significant to the recovery of these threatened species.

During July and August of 2021, CDFW and the National Marine Fisheries Science (NMFS) requested that the State Water Board pursue an emergency regulation to curtail water diversions in order to provide minimum drought emergency flows for the protection of native fish on Mill and Deer Creeks similar to actions taken during the last drought in 2014 and 2015. The State Water Board adopted an emergency regulation for Mill and Deer Creeks on September 22, 2021
