To: Shasta River Watershed Water Right Holders (sent to water right holders for which the Board has email addresses) and Interested Parties on Scott-Shasta Drought E-mail List
The State Water Resources Control Board (State Water Board or Board) issued Addendum 2 for the Shasta River Watershed Curtailment Order (WR 2024-0006-DWR), which suspends all curtailments for water rights in the Shasta River watershed. This means that the water right diverters noted in Attachment A to Addendum 2 may divert under their priority of right through October 31, 2024, unless the order is otherwise amended or superseded prior to this date.
Livestock Diversions
The Emergency Regulation (section 875.7) includes provisions related to inefficient surface water diversions for livestock watering. The provisions apply to everyone who diverts surface water for livestock during September 1, 2024 through January 31, 2025 (expiration of the current Regulation). The inefficient livestock watering requirement applies to all surface water diversions, no matter what priority. The following criteria must be met in the Shasta River watershed before diverting surface water for livestock:
- The diverter shall notify the State Water Board by email to: ScottShastaDrought@waterboards.ca.gov with: their Name, Water Right Number and point of diversion, anticipated diversion amount(s), and their plans to track compliance and maintain records.
- There are no active curtailments in the respective watershed. With this suspension, there are no active curtailments in the Shasta River watershed through October 31, 2024, unless this addendum is amended or superseded.
- The California Department of Fish and Wildlife (CDFW) has made determinations that flows have been sufficient to stimulate salmon migration.
- After September 1st for fall-run Chinook salmon (CDFW made this determination for the Shasta River watershed on October 24, 2024); and/or
- After November 1st for coho salmon.
- For diversions on tributaries below Dwinnell Dam, the relevant tributary is and remains connected to the mainstem.
- Except for diversions upstream of Dwinnell Dam, diversions are operated to bypass 90 percent of flow at the point of diversion, except that when flows in the Shasta River are greater than 220 cfs at the Yreka USGS gage the diversions may operate to bypass 80 percent of flow.
- The diversions are limited further if necessary to avoid disturbing redds.
On October 24, 2024, CDFW notified the State Water Board that it had made the determination that there has been sufficient flow to stimulate fall-run Chinook salmon migration into the Shasta River. With the temporary suspension of curtailments in the watershed, inefficient surface diversions for livestock are permissible when the remaining criteria are met.
