Sustainable Groundwater Management Act (SGMA)
The Sustainable Groundwater Management Act (SGMA), signed into law by Governor Jerry Brown, creates a statewide framework for the sustainable, local management of California’s groundwater.
SGMA, which became state law in 2014, directs local agencies to work together to develop local Groundwater Sustainability Plans (GSP) in basins and sub-basins classified by the state as medium or high priority.
BBID Becomes a Groundwater Sustainability Agency (GSA)
Following a public hearing in March 2017, Byron-Bethany Irrigation District’s Board of Directors voted unanimously to become a groundwater sustainability agency (GSA) for a portion of the Tracy Subbasin, which underlies the District’s service area in portions of Contra Costa, San Joaquin and Alameda Counties. The Tracy Subbasin has been classified as medium priority by the California Department of Water Resources (DWR).
As a GSA, the District will work cooperatively with surrounding agencies, cities and counties to manage groundwater in a responsible, sustainable manner.

What’s Next for BBID
As part of the resolution approved by the BBID Board, the District intends to develop groundwater sustainability plans for portions of the Tracy Subbasin within District boundaries in Contra Costa and San Joaquin Counties, and both within and outside BBID’s boundaries in Alameda County.
The Board voted to enter a memorandum of understanding (MOU) to work with multiple agencies within Contra Costa County.
In San Joaquin County, the District expects to collaborate with the City of Tracy to resolve overlaps in proposed GSA service areas.
In Alameda County, the District plans to pursue an agreement with Zone 7 Water Agency, in which Zone 7 would formally delegate to BBID its authority to manage groundwater within Zone 7’s service area.
Tracy Subbasin Boundary Modification
BBID is part of a coalition of eight local water agencies requesting a boundary modification of the Tracy Subbasin along county lines.
This will ensure that water users in Tracy and San Joaquin counties won’t exercise undue influence on how groundwater is managed in East Contra Costa County.
