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.

Coastal Change Hazards Portal

The Coastal Change Hazards Portal provides interactive access to coastal change science and data for our Nation’s coasts. Information and products are organized into three coastal change hazard themes: 1) extreme storms, 2) shoreline change, and 3) sea-level rise.

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.

Dissolved Solids Sources, Loads, and Yields For the Conterminous U.S.

Using the SPARROW (SPAtially-Referenced Regression on Watershed Attributes) model, long-term mean annual conditions for dissolved-solids sources, loads, and yields were predicted for nearly 66,000 stream reaches and their corresponding incremental catchments that drain the Nation.

Watershed Regressions for Pesticides (WARP)

The Watershed Regression for Pesticides (WARP) is an online tool that allows users to estimate pesticide concentrations for streams that have not been monitored. WARP models are developed using linear regression methods to establish quantitative linkages between measured pesticide concentrations and a variety of human-related and natural factors that affect pesticides in streams.

Volatile Organic Compounds in Samples from Domestic and Public Wells, 1985–2002

The U.S. Geological Survey’s (USGS) National Water-Quality Assessment (NAWQA) Program recently completed a national study of volatile organic compounds (VOCs) in the Nation’s ground water (Zogorski and others, 2006). Part of this assessment emphasizes the occurrence of 55 VOCs in samples from 2,401 domestic wells and 1,096 public wells during 1985–2002.

Current Streamflow and Water-Quality Monitoring at Select Sites in the Animas and San Juan River Basins, Colorado, New Mexico, and Utah

The USGS monitors current streamflow and water-quality conditions at various sites in the Animas and San Juan River Basins in Colorado, New Mexico, and Utah, including areas below the Gold King Mine release area. These streamgages provide continuous data on streamflow and select water-quality constituents including specific conductance, water temperature, pH, and turbidity.

Predicted pH at the domestic and public supply drinking water depths, Central Valley, California

This scientific investigations map is a product of the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) project modeling and mapping team. The prediction grids depicted in this map are of continuous pH and are intended to provide an understanding of groundwater-quality conditions at the domestic and public supply drinking water zones in the groundwater of the Central Valley.
