The PeakFQ application performs peak-flow frequency analysis to evaluate flood frequency on rivers and streams.

The Pennsylvania Drought Condition Web Tool shows the current drought status for each county and hydrologic conditions for precipitation, streamflow, groundwater levels, and Palmer Drought Index used by PADEP for drought monitoring.

The Philadelphia Water Department (PWD) and USGS have been working together to create and expand the water-quality monitoring network for Philadelphia. Data from these gaging stations will allow PWD scientists and engineers to monitor spatial and temporal water quality/quantity trends in support of watershed restoration initiatives occurring in Philadelphia.

Hawaiian coastal wetlands provide important habitat for endangered waterbirds and socio-cultural resources for Native Hawaiians. Currently, they are degraded by development, sedimentation, and invasive species and, thus, require restoration. Site prioritization represents both an actionable plan for coastal wetland restoration and an alternative protocol for restoration decision-making.

This tool shows the proportion of goose locations expected to be in or below a user-specified rotor-swept zone based on expected goose flight altitudes.

Inland recreational fishing is often conceived as primarily a leisure-driven activity in freshwaters, yet it can contribute substantially to food systems. This tool explores nutrition, economic value, and climate vulnerability of inland recreational consumption by country.

Learn how the U.S. Geological Survey (USGS) uses data and tools to facilitate the restoration and management of post-fire landscapes. This Story Map includes examples from fire sites within the Great Basin of the western U.S.

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.

Two continuous streamgages were installed in September 2019 during the first phase of this project and are currently in operation. Additional streamgages were installed in August 2020 and September 2021, followed by the installation of two additional streamgages in April 2024. These streamgages provide the Blackfeet Water Department and others with important water quantity information.

Surface water sites associated with the restoration effectiveness monitoring in the Vermilion River.

topoBuilder is a public web application released by the National Geospatial Program that enables users to request customized USGS-style topographic maps, known as an OnDemand Topo, that utilize the best available data from The National Map.

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.
