Hydrologic Unit Maps

The U.S. is sub-divided into successively smaller hydrologic units which are classified into four levels: regions, sub-regions, accounting units, and cataloging units. Each unit is identified by a unique hydrologic unit code (HUC) consisting of two to eight digits based on its classification. This site provides information and data for current and historical hydrologic units, names, and numbers.

USGS Flood Event Viewer

During large, 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.

Federal Priority Streamgages (FPS)

This mapper identifies USGS Federal Priority Streamgages (FPS). FPS are monitoring stations that track the amount of water in streams and rivers across the Nation to meet long-term federal information needs. They are strategically positioned to serve as a backbone for the larger National Streamflow Network that is operated in cooperation with over 1,200 federal, state, tribal, and local agencies.

Endangered, Discontinued, and Rescued Stations

This mapper identifies USGS streamgages that are in danger of being discontinued or converted to a reduced level of service due to lack of funding, gages that already have been discontinued, and gages that have been ‘rescued’ by a new funding source.

Principal Aquifers of the United States

A principal aquifer is defined as a regionally extensive aquifer or aquifer system that has the potential to be used as a source of potable water. This site provides downloadable maps (Ground Water Atlas of the United States, 2003) and spatial data (National Atlas, 2014) for the principal aquifers and aquifers of alluvial and glacial origin of the U.S.

USGS Flood Inundation Mapper

USGS Flood Inundation Maps, along with Internet information regarding current stage from the USGS streamgage, provide emergency management personnel and residents with information that is critical for flood-response activities, such as evacuations and road closures, as well as for post-flood recovery efforts.

Water-Quality Changes in the Nation's Streams and Rivers

This mapper provides results from the largest-ever assessment of water quality changes in the Nation's streams and rivers. More than 185 million water-quality records from over 600 Federal, State, Tribal, and local organizations were screened as part of this assessment.

Groundwater Quality: Decadal Change

Almost one-half of the U.S. population rely on groundwater for their water supply, and demand for groundwater for public supply, irrigation, and agriculture continues to increase. This mapper shows how concentrations of pesticides, nutrients, metals, and organic contaminants in groundwater are changing during decadal periods across the Nation.
