Areas of Land Subsidence in California

In California, land subsidence—mostly from groundwater pumping—was first documented by the USGS in the early 20th century. Completion of State and Federal water projects that bring water from California's wet north to its dry south allowed some groundwater aquifers to recover, and subsidence decreased in these areas. Subsidence continues today, sometimes at high rates of more than 1 foot/year.

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.

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.

National Biogeographic Map

The National Biogeographic Map (NBM) is a project of the Core Science Systems Mission Area. The project’s goal is to provide a platform for analysis of questions about what species are where, how well protected they are, how vulnerable they are to stressors, and what management options will have the greatest benefit for conservation of biodiversity.

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.
