What is a Groundwater Sustainability Plan (GSP)?

A Groundwater Sustainability Plan (GSP) or Alternative Plan is a document that outlines how the Groundwater Sustainability Agencies (GSAs) will implement, manage and measure the results of specific actions for the health and viability of the groundwater basin. The California Department of Water Resources (DWR) will evaluate GSPs or Alternative Plans to provide the GSA with an assessment of the plan and any necessary recommendations every five years following its establishment.
