Hydrogeology of the Adelaida Area, San Luis Obispo County, CA

To address stakeholder concerns that the increased demand for water use has, and will continue to, affect groundwater levels and availability in the Adelaida area, the County of San Luis Obispo Board of Supervisors has asked the USGS to conduct a comprehensive evaluation of groundwater resources of the Adelaida area. Use this interactive map to explore the hydrogeology of the Adelaida area, including land use, geology, and USGS hydrologic data by watershed or water management district. For more information on the study, please visit the project website.
