State Water Board Drought Year Water Actions

Notices of Water Availability (Curtailment AND EMERGENCY REGULATIONS)

The right to divert surface water in California is based on the type of right being claimed and the priority date. Water right permits specify the season of use, purpose of use and place of use for the quantity of water authorized under the permit or license. In times of drought and limited supply, the most recent (“junior”) right holder must be the first to discontinue use. Even more senior water right holders, such as some riparian and pre-1914 water right holders may also receive a notice to stop diverting water if their diversions are downstream of reservoirs releasing stored water and there is no natural flow available for diversion. In the coming weeks and months, if dry weather conditions persist, the State Water Board will notify certain water right holders in critically dry watersheds of the requirement to stop diverting water under their water right, based on their priority. These notices will be posted below.

  • Frequently Asked Questions about Curtailment

  • Clarification Regarding the use of Previously Stored Water by Water Right Holders Receiving Curtailment Notices
    Staff continues to receive questions regarding whether the use of water, previously stored under a water right, is subject to curtailment. The State Water Board’s curtailment of water rights does not limit the use of water previously stored in a pond or reservoir. Therefore, uses of previously stored water authorized by a permit, license, registration or certificate can continue. The curtailment notice restricts the water right holder’s ability to directly divert water or to collect water to storage, including to refill storage space lost to beneficial use.
