The Wyandotte Creek GSA has compiled the following collection of educational resources to help build a deeper understanding of groundwater science and the key sustainability indicators that guide groundwater management.

Resources are organized by topic area—including general groundwater concepts, subsidence, groundwater levels, interconnected surface water, water quality, and groundwater storage. Each section includes links to trusted sources such as the California Department of Water Resources (DWR), the United States Geological Survey (USGS), the National Ground Water Association (NGWA), and other state and federal agencies. You'll find a mix of introductory videos, interactive maps, fact sheets, data visualization tools, and technical references.
