Adelaida Area Hydrogeologic Study

The San Luis Obispo County Flood Control and Water Conservation District is coordinating with the U.S. Geological Survey (USGS) and the Upper Salinas-Las Tablas Resource Conservation District (RCD) to conduct a groundwater study in the Adelaida area west of the City of Paso Robles (click here to view an interactive map of the preliminary study area). The goal of this study is to provide a better understanding of the groundwater conditions in the Adelaida area so that informed decisions can be made about managing local water resources.

Data of interest for the study includes well construction information, groundwater level data, water use information, groundwater chemistry data, and geological data.

Interactive Map of the Preliminary Adelaida Study Area

Click here to access the Interactive Data Viewer for the preliminary Adelaida study area. This is an interactive mapping system to help you navigate around the study area by panning, zooming, or searching for a specific parcel or street address that you would like to locate. There are different map layers that can be shown and superimposed in this interactive mapping system such as boundaries of groundwater basins, cities, roads, or other entities by checking the layer names indicated on the left panel layer menu.

To search and locate a specific APN or street address on the map:

  1. Enter either the nine-digit parcel number (APN) including hyphens or the complete street address in the “Search...” bar on the upper right-hand corner of the map screen and then click on the search button to locate it. The APN or street address that you just entered will appear on the left panel and a location marker will show up on the map to identify the location.
  2. Click on the APN or street address name shown on the left panel layer menu will zoom in to the specified location for a close-up look.
