Sustainable Groundwater Management Act (SGMA) Water Year Type Dataset

The following dataset has been developed to assist the Groundwater Sustainability Agencies (GSAs) in their water budget development per the Groundwater Sustainability Plan Regulations §354.18. GSAs may choose to use this dataset but are not required. GSAs have the option to develop their own water year types based on best available data. For information on how the SGMA Water Year Type Dataset was developed, please see the SGMA Water Year Type Dataset Development Report.
