Final Released: January 22, 20145 year Plan to improve sustainability of CA’s Water Resources
California Water Action PlanGoals:
10 Broad Actions:
Reliability: Develop more reliable water supplies Restoration: Restore important species and habitat Resilience: Establish a more resilience, and sustainably managed
water resource system
1. Make Conservation a California Way of Life2. Increase Regional Self‐Reliance and IWM Across all Levels of Gov.3. Achieve the Co‐Equal Goals of the Delta Plan4. Protect and Restore Important Ecosystems5. Manage and Prepare for Dry Periods6. Expand Water Storage Capacity and Improve Groundwater Mgmt.7. Provide Safe Water for All Communities8. Increase Flood Protection9. Increase Operation and Regulatory Efficiency10. Identify Sustainable and Integrated Financing Opportunities

2014 Sustainable Groundwater Management Act
The Sustainable Groundwater Management Act of 2014
KEY PRINCIPLES Groundwater best managed at the local or regional
level, and local agencies should have the tools and authority they need to sustainably manage their resources.
When local or regional agencies cannot or will not manage their groundwater sustainably, the State will intervene until the local agencies develop and implement sustainable groundwater management plans. 17

The Sustainable Groundwater Management Act of 2014
KEY INTENDED OUTCOMES Establish effective local governance to protect
and manage groundwater basins
Achieve sustainable management of groundwater basins
Manage regional water resources for regional self-sufficiency and prepare for dry periods
18
Requires that a groundwater sustainability plan (GSP) be adopted for the most important groundwater basins in California
• Limited to “high & medium priority basins” 127 out of 515 basins in the state
• Adjudicated basins are exempt, except for minimal reporting
• “Low & very low priority” basins are exempt, though they are encouraged to adopt plans.
2014 Sustainable GW Management Legislation
* Initial Basin Priority = June, 2014 Results---
Basin Priority will be updated to Include impacts to habitat and stream flow
June 2014 Basin Prioritization Resultshttp://water.ca.gov/groundwater/casgem/basin_prioritization.cfm
Establishes a timetable for adoption of GSPs By 2017, local groundwater sustainability agencies (GSA) must be
identified. By 2020, overdrafted basins must be covered by a groundwater
sustainability plan (GSP). Other high & medium priority basins not in overdraft must have plans by 2022.
By 2040, each high & medium priority basin must achieve sustainability, though this can be extended by 10 years for good cause.

“Local agency” means any local public agency that has water supply, water management, or land us responsibilities within a groundwater basin.
2014 Sustainable GW Management Legislation
Exempts local groundwater sustainabilityplans (GSPs) from CEQA
Empowers local agencies to manage their basins sustainably Gives local agencies new authority to:
• Adopt and enforce rules, • Require registration of groundwater wells,• Measure and manage groundwater extraction,• Groundwater use reporting• Fee assessment• Request revisions of groundwater basin boundaries.
2014 Sustainable GW Management Legislation
Establishes Basic Requirements for GSPs: • Description of physical setting• Identification of groundwater conditions: (levels, quality,
subsidence, groundwater – surface water interaction)• Historic and projected water demands and supplies• Maps: basin and agency boundaries, recharge areas.• Measurable Objectives with Interim Milestones (every 5 yrs) to
achieve sustainability in 20 yrs.• Description of how GSP is given consideration in General Plans
• Undesirable Results• Chronic lowering of gw levels that result in significant and unreasonable
depletion of supply if continued over the planning and implementation horizon.
• Significant and unreasonable reduction in groundwater storage• Significant and unreasonable degradation of water quality• Significant and unreasonable land subsidence that significantly interferes
with surface land uses• Surface water depletions that have significant and unreasonable adverse
impacts on beneficial uses of surface water
2014 Sustainable GW Management LegislationKey Definitions
• Sustainable Groundwater Management“The management and use of groundwater in a manner that can be maintained during the planning and implementation horizon without causing undesirable results.”
• Subject to Critical Conditions of Overdraft“A basin is subject to critical conditions of overdraft when continuation of present water management practices would probably result in significant adverse overdraft-related environmental, social, or economic impacts.”
• Provides for a limited state role• DWR will evaluate groundwater sustainability plans within two
years of submission.• State Water Board may temporarily intervene in four limited
circumstance.• No governance structure for a basin after 2 ½ years• No plan after five years (overdrafted basins) or ten years
(other basins)• Plan is inadequate and the basin has serious groundwater
problems• Local agency has not adequately implemented the plan and
the basin has serious groundwater problems
• State Board must return control to local agencies as soon as they adopt an adequate plan.
• State Board may limit its temporary control to the portion of the basin not being managed.

Objectives:1. Groundwater sustainability agency governance and sensible
regulations
2. Provide Technical Assistance to GSAs
3. Provide Planning Assistance to GSAs
4. Provide interregional assistance to local agencies acknowledging interaction with adjacent basins
