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.

Geomorphic Reference Reach Data for the Kalamazoo River Basin, Michigan Area of Concern (ver. 2.0, October 2024) Geomorphic Reference Reach Data for the Kalamazoo River Basin, Michigan Area of Concern (ver. 2.0, October 2024)
The Kalamazoo River Area of Concern (AOC) in Michigan has multiple dams in various stages of removal. Following dam removal, river restoration activities will occur in impacted reaches. Hydrogeomorphic data from relatively undisturbed and hydraulically stable river reaches are commonly used to inform the design parameters of river restoration projects. Reference reaches should be...
Experimental Testing of Endangered Pallid Sturgeon to Viral Hemorrhagic Septicemia Virus Genotype IVb Experimental Testing of Endangered Pallid Sturgeon to Viral Hemorrhagic Septicemia Virus Genotype IVb
Viral hemorrhagic septicemia virus (VHSV) is an aquatic rhabdovirus causing severe disease in numerous freshwater and saltwater fish species. Initially the virus was been found to cause disease in European fish populations starting around 1938 and was first detected in North America in the late 1980s. Of the four VHSV genotypes (I, II, III, and IV), the North American subtype IVb...
Data Release: Mercury accumulation potential of aquatic plant species in West Dongting Lake, China Data Release: Mercury accumulation potential of aquatic plant species in West Dongting Lake, China
An ecological study on mercury contamination in the wetland of West Dongting Lake in China. This study measured the total mercury concentration in the soil and compared it to the measured total concentration of mercury in the above and below ground tissue of different plant species on the floodplain of West Dongting Lake. Bioconcentration, bioaccumulation, and translocation factors were...
Sentinel-1 and Sentinel-2 based frequency of open and vegetated water across the United States (2017-2021) Sentinel-1 and Sentinel-2 based frequency of open and vegetated water across the United States (2017-2021)
High-frequency observations of surface water at fine spatial scales are critical to effectively manage aquatic habitat, flood risk and water quality. We developed inundation algorithms for Sentinel-1 and Sentinel-2 across 12 sites within the conterminous United States (CONUS) covering greater than 536,000 km2 and representing diverse hydrologic and vegetation landscapes. These algorithms...
Rainy Lake and Namakan Reservoir shallow water bathymetric data, water surface elevations, and recovered high-water marks, 2022 Rainy Lake and Namakan Reservoir shallow water bathymetric data, water surface elevations, and recovered high-water marks, 2022
Bathymetric data were collected with a single-beam echosounder in 2022 for 18 selected shallow (0-3 meters) areas to improve a digital elevation model (DEM) for Rainy Lake and Namakan Reservoir created by Environment and Climate Change Canada. Bathymetric data were collected in transects spaced approximately 20 meters apart. In addition to the bathymetric data, the locations and...
