Groundwater Management

Todd Groundwater has participated in groundwater management since our founding, including development and implementation of plans in accordance with the original Groundwater Management Planning Act and now the landmark Sustainable Groundwater Management Act.

Groundwater management planning in California has been conducted primarily at the local level by water agencies, acting through their own respective authorities or through the 1992 Groundwater Management Planning Act as amended. Now, the Sustainable Groundwater Management Act of 2014 — building on previous legislation and increasing the responsibilities and powers of local water and land use agencies — provides the major framework for groundwater management.

The Sustainable Groundwater Management Act (SGMA) lays out a process and timeline, with specific requirements and deadlines, for local agencies to achieve sustainable groundwater management. Under the Act, a Groundwater Sustainability Agency (GSA) must be established for medium and high priority basins (as defined by the Department of Water Resources and excepting adjudicated basins).

Todd Groundwater currently is assisting agencies with planning for GSA establishment. The Act also requires that GSAs create and implement a Groundwater Sustainability Plan with required components (summarized below), many of which already are included in existing management plans.

Groundwater Sustainability Plan Components

  • Groundwater basin characterization
  • Presentation and discussion of historical data: groundwater levels, groundwater quality, subsidence, groundwater/surface water interaction, historical and projected water demands and supplies
  • Maps of basin area and boundaries, and recharge areas
  • Measurable management objectives to achieve sustainability
  • An implementation plan with milestones and reporting
  • Monitoring and management of groundwater levels, water quality, groundwater quality degradation, and inelastic land surface subsidence
  • Summary of monitoring and provision of monitoring protocols
  • Coordination with other applicable local government plans (e.g. General Plans)

Todd Groundwater has many years of experience in all aspects of preparing groundwater management plans and is already a pioneer in implementing the SGMA (see sidebar).

California's Department of Water Resources provides detailed information on the SGMA and related implementation activities, including the Initial Groundwater Basin Prioritization required by the SGMA.
