Merced Irrigation-Urban Groundwater Sustainability Agency (MIUGSA) Formation

The Sustainable Groundwater Management Act (SGMA) was passed in September of 2014 and became law on January 1, 2015. SGMA required all high and medium priority groundwater basins to be managed by one or more groundwater sustainability agencies (GSA). These GSA(s) will have the authority, and obligation, to develop one or more groundwater sustainability plans (GSP) that develops solutions for the long-term sustainable management of local groundwater resources.

Each groundwater subbasin was required to have all of its geographic area covered by one or more GSA(s) by June 30, 2017. MIUGSA was formed to sustainably manage the Merced Groundwater Subbasin, which is a Critically Overdrafted Basin (GSP due January 31, 2020).
