The Sites Project Authority is pursuing a water right permit from the State Water Resources Control Board (SWRCB), which will provide them legal authority to divert water within certain conditions, for a specific purpose, and for use within a specified area. The Authority will be the State designated steward of the water right for the Sites Reservoir Project.

Throughout the year-long application process, the Authority worked with SWRCB to provide the information needed to secure the Project’s water right permit:

  • On June 2, 2023, the State Water Board issued public notice of the water right application for the Sites Reservoir Project.
  • On May 5, 2023, the State Water Board deemed the amended application sufficient to proceed with public notice of the application.
  • On January 6, 2023, the Sites Project Authority submitted an amended application for the Sites Reservoir Project. The amended application can be accessed through the eWRIMS Database System.
  • On August 26, 2022, the State Water Board accepted the Sites Project Authority’s water right application and requested information missing from the application before proceeding forward with processing the application.
  • A water rights application (Application A025517X01) was filed by the Sites Project Authority for the Sites Reservoir Project on May 11, 2022. The application can be accessed through the eWRIMS Database System.
