TRAILS – Trail Routing, Analysis, and Information Linkage System is a trail planning and collaboration tool that utilizes geospatial analysis to determine potential routes for new trail connections or to reroute an existing trail.  

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

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.

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.

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.

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.  

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.

The U.S. Geological Survey National Produced Waters Geochemical Database Viewer (ver. 3.0) provides access to an updated compilation of geochemical and related information for water from oil and gas wells in the United States. The information includes identification and location information, well descriptions, dates, rock properties, physical properties of the water, organic chemistry and more.

This tool shows the presence of aquatic chlorophyll-a in select waterbodies. Note: This tool indicates the presence of aquatic chlorophyll-a and should not be used to determine if a toxic cyanobacterial bloom (harmful algal bloom) is present. 

The Baseflow Forecast Web Tool allows you to access baseflow forecasts at thousands of locations across the Nation.
