Sustainable Groundwater Management Act

Sustainable Groundwater Management Act graphicFramework

The California Legislature enacted comprehensive legislation aimed at strengthening local control and management of groundwater basins throughout the state. Gov. Jerry Brown signed the three-bill package into law on Sept. 16, 2014.

Known as the Sustainable Groundwater Management Act of 2014, the legislation provides a framework for sustainable management of groundwater supplies by local authorities, with a limited role for state intervention when necessary to protect the resource. More information can be found on the State Water Board website.

Key Steps on the Road to Sustainability

The legislation lays out a process and a timeline for local authorities to achieve sustainable management of groundwater
basins. It also provides tools, authorities and deadlines to take the necessary steps to achieve the goal. For local agencies
involved in implementation, the requirements are significant and can be expected to take years to accomplish.

  • Step one: Local agencies must form local groundwater sustainability agencies (GSAs) within two years.
  • Step two: Agencies in basins deemed high- or medium-priority must adopt groundwater sustainability plans (GSPs) within five to seven years, depending on whether a basin is in critical overdraft.
  • Step three: Once plans are in place, local agencies have 20 years to fully implement them and achieve the sustainability goal.
  • State role: The State Water Resources Control Board may intervene if locals do not form a GSA and / or fail to adopt and implement a GSP.

New Tools for Local Agencies

The legislation gives local agencies new tools to manage groundwater sustainably.
For example, groundwater sustainability agencies may:

  • Require registration of wells and measurement of extractions
  • Require annual extraction reports
  • Impose limits on extractions from individual groundwater wells
  • Assess fees to implement local groundwater management plans
  • Request a revision of basin boundaries, including establishing new subbasins

Creation of Groundwater Sustainability Plans

The legislation provides options for local agencies to develop the required groundwater sustainability plans. Agencies may opt to create a single plan covering the entire basin, or knit together multiple plans created by multiple agencies.

A plan must include measurable objectives and interim milestones to achieve the sustainability goal for the basin within a 20-year time frame. The plan also must include a physical description of the basin, including information on groundwater levels, groundwater quality, subsidence and groundwater-surface water interaction; historical and projected data on water demands and supplies; monitoring and management provisions; and a description of how the plan will affect other plans, including county and city general plans.
