Welcome to the East Bay Plain Subbasin Data Management System (DMS)

Welcome to the East Bay Plain Subbasin Data Management System (DMS)

The DMS contains tools for visualization and analysis developed as part of the Groundwater Sustainability Plan for the East Bay Plain Subbasin that are intended to support sustainable groundwater management practices, promote transparency, and satisfy California Code of Regulations Section 352.6.

Data in the DMS was collected and compiled from publicly available sources, and does not include wells currently used for production and may include wells historically used for monitoring that no longer exist. Data is subject to change at any time.

For questions, please use the ‘Contact Us’ link on the lower left-hand corner of the DMS, or use this link.

Thank you for your inquiry. Your message will be sent to EBMUD and City of Hayward and staff will be in touch.
List of Acronyms & Abbreviations
For a broader list of acronyms and abbreviations, see the GSP here
  • MO = measurable objective(s)
    • Definition: “Measurable objectives” refer to specific, quantifiable goals for the maintenance or improvement of specified groundwater conditions that have been included in an adopted Plan to achieve the sustainability goal for the basin.
  • MT = minimum threshold(s)
    • Definition: “Minimum threshold” refers to a numeric value for each sustainability indicator used to define undesirable results.
  • RMS = representative monitoring site
    • Definition: “Representative monitoring site” refers to a monitoring site within a broader network of sites that typifies one or more conditions within the basin or an area of the basin.
  • EBP = East Bay Plain
    • Definition: EBP = East Bay Plain: Groundwater subbasin 2-009.04 as defined in DWR Bulletin 118 update 2020.

  • SGMA = Sustainable Groundwater Management Act of 2014
  • Hayward = City of Hayward
  • EBMUD = East Bay Municipal Utility District
  • USGS = United States Geological Survey
  • DWR = (California) Department of Water Resources
