SGMA - Depletions of Interconnected Surface Water
The Depletions of Interconnected Surface Water (ISW) dataset has been established to provide technical resources in support of Groundwater Sustainability Agencies (GSAs) as they develop and update their Groundwater Sustainability Plans (GSPs) under the Sustainable Groundwater Management Act (SGMA). The Department of Water Resources will post information and resources here, including three technical papers which provide informational resources to help identify, understand, and communicate the nature, occurrence, and estimation of depletions of ISW.
