Groundwater Management Plan Information

Major Recommendations

Local or regional agencies should develop groundwater management plans if
groundwater constitutes part of their water supply. Management objectives should be
developed to maintain a sustainable long-term supply for multiple beneficial uses.
Management should integrate water quantity and quality, groundwater and surface
water, and recharge area protection.

• Groundwater management in California is a local agency responsibility.
• In basins where there is more than one management agency, those agencies should
coordinate their management objectives and program activities.
• A water budget should be completed that includes recharge, extraction and change in
storage in the aquifer(s).
• Changes in groundwater quality should be monitored and evaluated.
• Stakeholders should be identified and included in development of groundwater
management plans.
