What is a Groundwater Sustainability Plan (GSP)?

All GSA’s must prepare a Groundwater Sustainability Plan (GSP) which defines a course to achieve sustainable groundwater management within 20 years of plan implementation. Plans must identify when and where groundwater conditions cause problems, such as subsidence; the specific projects and management actions that local agencies will implement to prevent the problems; and milestones to track plan progress. Plans must also describe how local agencies will monitor groundwater and how monitoring data will be used to improve conditions in the basin.
