Since 2019, the USGS Pennsylvania Water Science Center has been cooperating with York County, Pennsylvania to implement in-stream monitoring and water-quality sampling to compute, in real time, the concentration, loads, and yields of total nitrogen, total phosphorus, and suspended sediment for 6 major watersheds in the County.

Geoheritage lies at the intersection of science and society and is a term applied to significant or unique geologic features representing the values that we as a Nation place on them. These geologic features are recognized for their scientific, educational, cultural, economic, and aesthetic values.

Explore real-time soil moisture data by clicking on each point. Access site-specific USGS NWIS Water Data pages for time-series data on soil temperature, electrical conductance, and moisture. Some sites also include NRCS soil profile descriptions.

The Walker Basin Hydro Mapper web application provides a basin-wide view of real-time streamflow and reservoir storage capacity for the Walker River Basin in Nevada and California.

The Invasive Carp Open Data Hub is a platform for exploring and accessing USGS data, tools, applications, and publications related to invasive carp research and management.

Identifying areas expected to remain buffered from climate change and maintain biodiversity and ecological function is important for climate adaptation planning. As structurally diverse transitional zones between terrestrial and aquatic environments, riparian areas are often biological hotspots and provide critical corridors for species movement, particularly in arid and semi-arid regions.

This app displays historical total chlorophyll observations at U.S. Geological Survey (USGS) gaging stations, forecasts from the USGS models currently submitted to the Ecological Forecasting Initiative (EFI)-USGS River Chlorophyll Forecasting Challenge, and forecasted driver data used to create the models in a user-friendly interface.

A web-based interactive map that combines the national landslide inventory compilation with the national landslide susceptibility map. This searchable map integrates contributions from various local, state, and federal agencies and offers links to the original digital inventory files for more detailed information.

USGS, in cooperation with the Pennsylvania Department of Environmental Protection (PaDEP), has released a geonarrative detailing the sampling of a network of surface water sites across Pennsylvania.

The Geologic Hydrogen Prospectivity Map Explorer hosts various geologic and geophysical data layers in support of the U.S. Geological Survey’s initiative to map the potential of geologic hydrogen within the conterminous U.S. This first-ever Hydrogen Map Explorer contains 19 input maps and 7 integrated maps that highlight prospective areas for naturally occurring hydrogen across the country.

This interactive website highlights key scientific findings of the National Water Availability Assessment report through engaging stories, plain-language explanations, and interactive data visualizations.

The National Water Availability Assessment Data Companion (NWDC) delivers model-based estimates of water supply and demand.
