An interactive geonarrative (Esri Story Map) showing 62 field trip stops for exploring the Hayward Fault in the East San Francisco Bay Region of California.

Search and identify Cooperative Research Unit Program federal scientists based on their expertise with various topics and taxon.

WaterMAP, or Water Monitoring Above the Planet, is an interactive web application that brings together surface water observations across the U.S. The application allows users to explore water conditions over time using both remotely sensed satellite and field measured data.

REACT: Satellite monitoring of aquatic chlorophyll-a in select Idaho and Texas waterbodies

This application allows you to explore locations of recent USGS assessments of undiscovered oil and gas resources around the world. You can explore by continuous or conventional assessments by using the radio buttons located within the publications panel.

This Long Island Sound Partnership Compound Flood Hazard Web Map Application presents individual and combined flood hazard scores from rainfall, coastal storm surge and shallow or emerging groundwater on a 900-meter by 900-meter grid over a study area which encompasses New York City, and Long Island, and Long Island Sound Watersheds in Southeastern New York and Southern Connecticut.

This web application shows the status of monthly streamflow data at streamgages in New England relative to monthly site statistics for each gage.

This web application provides the latest streamflow values for U.S. Geological Survey (USGS) streamgages in Maine relative to seasonal aquatic base flows.

The Humboldt Capture Query Tool (HCQT) is an interactive application that helps water managers, scientists, and public stakeholders explore how groundwater pumping affects streamflow and other water sources across the Humboldt River Basin.

During major storms or other short-term events, the USGS collects streamflow and additional data (including storm tide, wave height, high-water marks, and additional sensor deployments) to aid in documenting flood events. The USGS Flood Event Viewer provides convenient, map-based access to downloadable event-based data.

Annual Water Data Reports were published annually for many decades as static archival products that supplemented direct access to current and historical water data provided by the USGS. These formal publications have been discontinued, but historical reports and modern replacements are available.
