This water demand reduction and supply monitor was developed by the Bay Area Regional Reliability (BARR) Partnership, a collaboration of eight Bay Area water agencies working together to improve regional water supply reliability.
A map of the demand reduction actions for each Bay Area agency/supplier is shown below to provide information on the calls for voluntary or mandatory water use reduction.
Bay Area water providers regularly monitor supply conditions to inform water management actions, as described in the BARR Drought Contingency Plan. The water supply map below reflects supply conditions for individual BARR agencies and some water suppliers in the North Bay Area as of April 26, 2022, based on Water Shortage Contingency Plan (WSCP) stages defined in Senate Bill (SB) 606—i.e., supply thresholds/triggers and associated actions, unique to each agency. Lower stages indicate less risk of a shortage, while higher stages indicate shortages of varying degrees. This is a voluntary effort at this time as compliance with SB 606 is not required until July 2022.
The water demand reduction and supply conditions maps are updated at least once a year and represent a snapshot in time, but agencies regularly monitor their supplies and update their individual websites (linked below) to reflect current conditions and calls for voluntary or mandatory demand reductions.
