Status of Groundwater Management in California Map (December 2004) - A map of California showing locations of adopted groundwater management plans, adjudicated basins, special act districts, and counties with adopted groundwater management ordinances and accompanying tables for each item listed.

Groundwater Management Table Links
The following tables compile links to different types of groundwater management agencies, plans, and ordinances. (The links reference sites or files outside the Groundwater Information Center and may link to general code sections or large files not maintained by DWR)

Adopted Groundwater Management Plans generally utilize existing government bodies and authority to proactively monitor and manage groundwater resource issues. The State of California encourages coordinated, basin wide, local agency management of groundwater resource per section 10755.2 of the California Water Code.
Adjudicated Basins are managed by court decree, typically where overlying stakeholders cannot come to agreement over hydrogeologic operations or resources.
Special Act Districts are authorized by acts of the Legislature and are provided special authorities and conditions under the law.
County Ordinances utilize the land use planning and police powers of locally elected county boards to address groundwater management to varying degrees and in different forms and contexts.
