Intermountain West Seamless Geologic Map Explorer

The Intermountain West Seamless Geologic Map Explorer is an interactive mapping application that hosts surficial and bedrock geologic data layers for a transect from the Rio Grande rift to the Basin and Range. 

USGS Upper Klamath Basin Well Mapper

This mapper identifies wells that are monitored in the Upper Klamath Basin Oregon and California by U.S. Geological Survey (USGS), Oregon Water Resources Department (OWRD), and California Department of Water Resources (CDWR). This web page provides access to current and historic groundwater-level data collected by those agencies, as well as water-level graphs and maps.

Transboundary Watersheds Geonarrative

Explore the geonarrative highlighting USGS research activities in transboundary watersheds in the northwest. The USGS is establishing baseline water quality conditions in rivers that cross the US-Canadian border.

USGS Trails Explorer

The USGS Trails Explorer visualizes the current distribution of aggerated trails.  

Coastal Salinity Index

The location of the freshwater–saltwater interface along the coast is an important factor in the ecological and socioeconomic dynamics of coastal communities. Salinity is a critical response variable that integrates hydrologic and coastal dynamics including sea level, tides, winds, precipitation, streamflow, and tropical storms.

Triangle study area and data

Map and data links associated with this project.

Floodplain Ecosystem Service Mapper

Healthy floodplains and wetlands provide critical ecosystem services to local and downstream communities by retaining sediments, nutrients, and floodwaters. Land conversion and degradation diminish floodplain functionality and services.

Georgia Water Use

The U.S. Geological Survey (USGS) South Atlantic Water Science Center and the Environmental Protection Division of the Georgia Department of Natural Resources have been collecting and compiling water-use information in Georgia since 1980 as part of an ongoing cooperative agreement.

Groundwater Conditions of Georgia

The Groundwater Conditions of Georgia web tool has interactive maps and graphs, that calculate water level trends over time. The application is a continuation of a series of reports begun in 1978.  

Colorado River Basin drought and the 2023 water year

How wet was 2023 when compared to historical averages? This geonarrative compares precipitation and streamflow amounts observed during the 2023 water year with historical conditions in the Colorado River Basin over the last 30 years. While the 2023 water year was a wet year with above-average precipitation at many locations, it was not uniformly good or record-setting. 

Alaska Geochemical Database

The Alaska Geochemical Database Version 4.0 (AGDB4) contains geochemical data compilations in which each geologic material sample has one “best value” determination for each analyzed species. Best values are for mineral exploration and assessment purposes and should not be assumed to be appropriate for other uses.
