Paso Basin Aerial Groundwater Mapping Pilot Study

In November 2019, the County of San Luis Obispo joined two other California counties in a pilot study through Stanford University using innovative technology that could change the way California collects information about groundwater basins. The data collected will also help the Paso Basin Groundwater Sustainability Agencies comply with California’s Sustainable Groundwater Management Act.
