Shasta River Watershed Curtailment Orders and Addendums for 2025 Scott-Shasta Emergency Regulations

Curtailment Status:

Shasta Watershed- Opportunity to divert for Inefficient Livestock Watering: On October 14, 2025, California Department of Fish and Wildlife (CDFW) made the determination that flows have been sufficient to stimulate the Chinook salmon migration into Shasta River. This means that large livestock diversions may be possible in the Scott River and Shasta River watersheds until October 31, 2025, so long as other conditions are met, including connectivity, bypass, and notification conditions.  After November 1, no diversions for inefficient livestock watering are allowed until CDFW finds that sufficient flows to stimulate coho have occurred. Parties that want to divert for livestock need to confirm all the criteria outlined in the Emergency Regulation is met before diverting surface water for livestock.

Shasta River Watershed Curtailment Status:Effective October 15, 2025, as ordered in Addendum 5 to Order WR 2024-0006-DWR, all curtailments are suspended in the Shasta River watershed, unless and until Order WR 2024-0006-DWR is further updated. If you plan to divert surface water for inefficient livestock irrigation, it is required that the necessary criteria be met as outlined in the Addendum and Emergency Regulation section 875.7. (b).
