Interactive Maps

The Geochemical Data Portal assembles, reformats, corrects, and archives data obtained from the geochemical analysis of geologic samples collected for USGS and Department of Energy studies.

This interactive web application allows you to explore, filter, and download subsets of the Energy Geochemistry Database (EGDB). The EGDB contains analytical data for samples collected by the Energy Resources Program (ERP) to develop an understanding of the physical and geochemical processes responsible for hydrocarbon formation.

The Central Valley has four hydrologic regions, from north to south: the Sacramento Valley, the Delta & Eastside Streams, the San Joaquin Basin, and the Tulare Basin. Water flows from Sacramento Valley, Tulare Basin, and the San Joaquin Basin, into the Delta & Eastside Streams through the Central Valley's only natural outlet, the Carquinez Strait, on its way to the Pacific Ocean.

The Central Valley Hydrologic Model version 2 (CVHM2) is an integrated surface–subsurface hydrologic model, representing the major components of the hydrologic system of California’s Central Valley. This new decision support tool is useful for testing water management strategies in California's Central Valley.

This Interactive Atlas of Critical Minerals shows you where critical minerals are produced. Discover which countries produce critical minerals, what percent of the world production they are responsible for, and details on what each mineral is used for.

The USGS-DOE Cooperative Studies and Groundwater Monitoring in Nevada website provides an interactive and easy-to-use interface to access groundwater levels, groundwater withdrawal, and water-temperature data for wells on and adjacent to the NNSS.
