Data Access Tools

Interactive access to coastal change science and data for our Nation’s coasts. Information and products are organized within three coastal change hazard themes: 1) extreme storms, 2) shoreline change, and 3) sea-level rise. Displays probabilities of coastal erosion.

The National Water Dashboard (NWD) is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.

TroutCast is an interactive tool that helps users explore the projected impacts of drought on valuable trout fisheries in the northern Rocky Mountains. TroutCast provides insights into how these changes are affecting Montana's renowned blue-ribbon trout fisheries, supporting proactive management and sustainable recreational fishing for anglers today and generations to come.

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

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.

The National Petroleum Reserve-Alaska (NPRA) Legacy Data Archive contains geological and geophysical data collected during two extensive exploration programs, the first conducted by the U.S. Navy between 1944 and 1953 and a second conducted by the U.S. Geological Survey (USGS) from 1974 to 1982.

The U.S. Geological Survey uses a depiction and classification scheme for hydrologic units known as hydrologic unit codes (HUCs). HUCs generally represent catchments, and river basins are represented by a unique series of numbers with successively smaller hydrologic units nested inside of larger ones.

Interactive mapping of groundwater levels.

The Land Treatment Digital Library (LTDL) was created by the U.S. Geological Survey to catalog legacy land treatment information on Bureau of Land Management lands in the western United States. The LTDL currently houses thousands of treatments from BLM lands across 10 states.
