This week in… State Board Curtailment Orders

The State Water Resources Control Board has lifted the curtailment orders on most water diversions in the state. These curtailment orders had been issued this May and June to more than 10,000 post-1914 water rights holders in order to protect the rights of senior water rights holders as well as downstream riparian users. Curtailment orders remain in effect in Scott River in Siskiyou County and Deer Creek in Tehama County.

The State Board said the curtailments have been lifted because of recent rainfall and reduced demand. Precipitation for this water year remains below average in most of the state, except in certain parts of northern California and areas of Monterey, Kings, and Tulare Counties.















In other news…

  • The San Diego City Council unanimously voted to approve a $2.5 billion project to recycle wastewater into drinking water.
  • A new report suggests that California’s waters system could probably only utilize about six million acre-feet of additional storage. Additional storage beyond that amount would be limited by precipitation and the water transportation system.
