The Department of Water Resources (DWR) has developed a Strategic Plan for its Sustainable Groundwater Management (SGM) Program. DWR’s SGM Program will implement the new and expanded responsibilities identified in the 2014 Sustainable Groundwater Management Act (SGMA). Some of these expanded responsibilities include: (1) developing regulations to revise groundwater basin boundaries; (2) adopting regulations for evaluating and implementing Groundwater Sustainability Plans (GSPs) and coordination agreements; (3) identifying basins subject to critical conditions of overdraft; (4) identifying water available for groundwater replenishment; and (5) publishing best management practices for the sustainable management of groundwater.


New!GSA Notification Received
DWR has received a notification of formation of a Groundwater Sustainability Agency. View the notification here.

New!DWR has updated the GSA Interactive Map to reflect the 2016 Basin Boundaries
A new map layer shows the areas that have been either added to or removed from a basin, which may affect a local agency's posted GSA notice. DWR will be updating the GSA Formation Table soon, but may first need to coordinate with a local agency or GSA to confirm the basin(s) that an agency intends to manage. Additional information may be requested from a local agency that has already submitted a GSA formation notice. View the GSA interactive Map here.

New!Final 2016 Basin Boundaries Now Available
The Bulletin 118 groundwater basin boundary modification process is now complete. The Final 2016 Basin Boundaries have been released and are now available for download. Download a zipped shapefile of the boundaries here (meant for use in GIS applications). Download a KMZ of the boundaries (meant for use in Google Earth) here.

GSP Emergency Regulations Guide Available
The Final GSP Emergency Regulations Guide is now available online. Access it here.

DWR Posts Notice of Proposed Emergency Regulatory Action
DWR proposes an emergency rulemaking action under the Administrative Procedure Act that would make the regulations that establish a process by which local agencies will establish Groundwater Sustainability Plans and Alternatives effective. View the notice here. View the finding of emergency here.

DWR has developed a Draft Strategic Plan for its Sustainable Groundwater Management Program. The draft plan describes DWR's responsibilities and vision for carrying out the Sustainable Groundwater Management Act, a package of laws that aim to protect the groundwater basins that provide more than half of the water Californians use in dry years. The draft plan outlines key actions DWR will undertake over the next several years to position itself to better support local agencies across California to achieve sustainable groundwater management.

The California Groundwater website offers links to partners involved in the SGMA implementation, multi-agency news and information, a groundwater blog, and the text of the SGMA legislation. More info…
