Coastal Salinity Index 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.

Floodplain Ecosystem Service Mapper 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 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 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 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.
