Triggering Criteria & Drought Response

Section VI: Triggering Criteria for Initiation and Termination Drought Response Stages

the District General Manager, or his/her designee, shall monitor water supply and/or demand conditions and shall determine when conditions warrant initiation of each stage of the Plan. Public notification of the initiation or termination of drought response stages shall be by one or all of the following: posted on the District’s public bulletin board, local newspaper, by mail, television, email or contact by District personnel.

A maximum of 50,000 acre feet released for District use per year based on thirty year average provided by U.S. Geological Survey official data. Volume can be adjusted with Board approval.
