Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Milwaukee River environmental DNA data for bigheaded carp and four other species from 2021 and 2022 Milwaukee River environmental DNA data for bigheaded carp and four other species from 2021 and 2022
An eDNA-based sampling approach used by the U.S. Fish and Wildlife Service for bigheaded carp Hypophthalmichthys spp. in the upper Mississippi River and Great Lakes Basins that collects hundreds of water samples per event. The U.S. Fish and Wildlife Service detected a single positive sample for bighead carp _H. nobilis_ during the spring 2021 sampling event in the Kinnickinnic River...
Oblique Aerial Photographs from October 13 and 17, 2024, of Landslides and Flooding Caused by Hurricane Helene (ver 1.1, March 2025) Oblique Aerial Photographs from October 13 and 17, 2024, of Landslides and Flooding Caused by Hurricane Helene (ver 1.1, March 2025)
This data release consists of geotagged oblique aerial photographs taken by U.S. Geological Survey (USGS) scientists to support landslide situational awareness following Hurricane Helene under mission assignment from the Federal Emergency Management Agency (FEMA). The data release is accompanied by a photo viewer map where select photos can be viewed interactively. The photographs were...
Data to Support the Evaluation of Alternative Coatings for USGS Water-Quality Samplers Data to Support the Evaluation of Alternative Coatings for USGS Water-Quality Samplers
A series of blank samples were analyzed as part of a study to evaluate alternative coatings for USGS water-quality samplers. The open-file report to be published in association with this data is titled "Evaluation of Alternative Coatings for U.S. Geological Survey Water-Quality Samplers" (Thornton, 2025) and includes further details of the study. The five coating options evaluated were...
Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay Nontidal Network stations: Water years 1985-2023 Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay Nontidal Network stations: Water years 1985-2023
Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in rivers across the Chesapeake Bay watershed were calculated using monitoring data from the Chesapeake Bay Nontidal Network (NTN) stations for the period 1985 through 2023. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted...
Juvenile carp survival rates relative to season, habitat and predator species combinations in experimental pond exposures Juvenile carp survival rates relative to season, habitat and predator species combinations in experimental pond exposures
Prey survival rates relative to season, habitat and species of predator from eighteen two-week experiments, from April-October in 2015 and 2016, that were conducted in experimental ponds with differing habitats of artificial structure, vegetation, or no habitat combinations.
Paired Watershed and Characteristic Trait Data for the Los Planes Basin Research Ranch Watersheds: U.S. Geological Survey Data Release Paired Watershed and Characteristic Trait Data for the Los Planes Basin Research Ranch Watersheds: U.S. Geological Survey Data Release
Watershed pairing is an approach used to assess effects of restoration on a landscape by comparing conditions across a treatment watershed and a control watershed, and then quantifying the differences. When the watersheds are statistically paired, the control watershed can serve as a baseline of conditions compared to the treatment watershed. We apply a watershed pairing analysis across...
