GIS Data
USGS is a primary source of geographic information system (GIS) data. Our data and information is presented in spatial and geographic formats, including The National Map, Earth Explorer, GloVIS, LandsatLook, and much more.
GAMA Priority Basin Project Groundwater-Quality Results: Assessment and Trends
This interactive webmap plots water-quality data from domestic and public-supply wells sampled by the USGS for the California Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project (GAMA-PBP), and allows users to download datasets. The GAMA-PBP is a cooperative program between the California State Water Resources Control Board and the U.S. Geological Survey.
Mojave Groundwater Data
Interactive map of the Mojave and Morongo groundwater basins. Data layers include sites and data for groundwater levels, water quality, and land subsidence. Groundwater data spans 1994 to the present.
The National Map
The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response. The National Map is easily accessible for display on the internet, as products and services, and as downloadable data.
Water Quality Data Viewer for New York
U.S. Geological Survey (USGS) scientists are leading a diverse range of studies to address CyanoHAB issues in water bodies throughout the United States, using a combination of traditional methods and emerging technologies, and in collaboration with numerous partners.
California Groundwater Model Archive
The USGS models shown on this site are in the public domain, and are freely available. They are based on MODFLOW and other public-domain USGS software. Links to publications and web resources associated with each model are shown in the table next to the model map. The associated model files for some of these models are currently available via download.
Telemetry of Cinnamon Teal Tagged in Sacramento NWR
Scientists at WERC's Dixon Field station have fitted Cinnamon Teal with GPS backpacks. Using R, the telemetry locations are displayed on an image every two weeks.
Edwards and Trinity Geology in Parts of South Central Texas
Groundwater flow and storage in the Edwards and Trinity aquifers are largely controlled by the geologic structure and hydrostratigraphy in the region. To help local agencies and stakeholders to more effectively manage the regional water resources, a better understanding of the spatial distribution of the geologic framework and hydrostratigraphic units of the aquifers is needed.
Nonindigenous Aquatic Species Quagga Mussel Sightings Map
Interactive map of the distribution of quagga mussels in North America. This map is provided by the USGS Nonindigenous Aquatic Species program.
Nonindigenous Aquatic Species Zebra Mussel Sightings Map
Interactive map of the distribution of zebra mussels in North America. This map is provided by the USGS Nonindigenous Aquatic Species program.
