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.

The USGS-NNSS Regional Groundwater Explorer web application is a user-friendly and interactive interface that provides access to a comprehensive database of groundwater levels, hydrologic conditions, construction, and descriptive narratives for wells on and adjacent to the NNSS.

The USGS Real-Time Flood Impact Map helps communities stay safe by providing real-time information and visuals about locations in their area that may be experiencing flooding.

These data and application are provided as part of USGS research on contaminants in surface waters across the United States and supported by the USGS Water Mission Area Proxies Project and the USGS Ecosystem Mission Area Environmental Health Program (Toxic Substances Hydrology).

The Environmental Strontium Isotope Web Map is an interactive mapping application for displaying strontium isotope data in environmental materials (for example, waters) in geographic relation to underlying bedrock geology that drives the isotope composition. Together, these data form the basis for isotopic fingerprinting applications in geologic, hydrologic, ecologic, and forensic science.

Annual Joint Agency Commercial Imagery Evaluation (JACIE) workshops engage federal agencies, their partners, and the commercial remote sensing industry to understand the characteristics and capabilities of current and new data sources, along with the quality of data they provide. This tool allows the searching of presentations from the workshops, that started in 2001.

Emergence of avian influenza viruses with the potential to be highly pathogenic to poultry, wild birds, & humans, such as the highly pathogenic H5N1 and H7N9 cause serious concern for the global economic & public health sectors. Visual representations of model data can be effective in helping to discover how the spread of the virus is influenced by environmental & human

The EarthNow! Landsat Image Viewer displays imagery in near real-time as Landsat satellites orbit the Earth. Along with the near real-time video stream, EarthNow! also replays acquisition recordings from previous Landsat overpasses. When Landsat satellites are out of viewing range of a ground station, the most recent overpass is displayed.
