Edisto-Santee River Basin
The Edisto-Santee River Basin is a primary focus area for the USGS South Atlantic Water Science Center (SAWSC). Follow through the geonarrative to learn about the basin and SAWSC's top 10 science highlights.
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.
Sparrow Modeling North Carolina Watersheds Mapper
The USGS developed the SPARROW (SPAtially Referenced Regressions On Watershed attributes) modeling framework to relate water-quality monitoring data to upstream nutrient and sediment sources and watershed characteristics. The mapper can be used to evaluate alternative hypotheses about the relative importance of various pollutant sources.
Triangle study area and data

North Carolina Rainfall Map
Map of North Carolina rain gages with National Weather Service precipitation overlays.
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.
USGS Science Collaboration Portal for the Colorado River Basin
To help resource managers plan and mitigate long-term drought impacts in the Colorado River Basin, the USGS has launched a platform that brings together science, data, and mapping and analytical tools from across the basin in a central location.

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.
Colorado Three Lakes System
The Three Lakes System of Colorado includes Grand Lake, Shadow Mountain Reservoir, and Granby Reservoir. This system is located within the headwaters of the Upper Colorado River Basin near the west entrance of Rocky Mountain National Park. This geonarrative focuses primarily on the drainage basin of the Three Lakes System and the Colorado River downstream to Windy Gap Reservoir.
