In January 2001, the San Timoteo Watershed Management Authority was created as a joint powers agency between the Beaumont-Cherry Valley Water District, the City of Beaumont, South Mesa Water Company and the Yucaipa Valley Water District.  The parties recognized that they all had common interests in managing the water resources of the San Timoteo Watershed and the Beaumont groundwater basin. 

Once formed, the San Timoteo Watershed Management Authority began a multi-phased effort to develop and implement a comprehensive water management program based on the following regional goals:

  • To optimize and enhance the local water supplies;
  • To protect high quality water resources; and
  • To equitably distribute the benefits and costs of developing a regional management strategy.

As a result of the desire to actively manage the local water resources, the parties executed a Stipulated Judgment that provided both the authority and responsibility for the administration of adjudicated water rights within the Beaumont Groundwater Basin.  The Honorable Judge Gary Tranbarger of the Superior Court of the State of California for the County of Riverside, signed the Judgment entitled “San Timoteo Watershed Management Authority, vs. City of Banning, et al.,” Case No. RIC 389197, on February 4, 2004.  (view Amended Judgment - March 14, 2019)

Pursuant to the Judgment, the Court appointed a five-member Watermaster committee consisting of representatives from the City of Banning, the City of Beaumont, the Beaumont-Cherry Valley Water District, the Yucaipa Valley Water District, and South Mesa Mutual Water Company.  While the Judgment assigns the management of the Beaumont Basin to the Beaumont Basin Watermaster, the Court retains continuing jurisdiction should there be any need in the future to resolve difficult issues between the parties.
