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.

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.
