A data release containing information on macroinvertebrate communities and sediment toxicity in the Buffalo River Area of Concern (AOC) and reference areas immediately upstream of the AOC collected during 2017 and 2020. Macroinvertebrate community samples were collected using bottom-deployed multiplate artificial substrate samplers and organisms were identified to the lowest practical taxonomic resolution and used to calculate metrics of biological integrity following standard New York State Department of Environmental Conservation procedures. Bed sediments were collected using a petite Ponar dredge and used for toxicity tests with two test species, Chironomus dilutus and Hyalella azteca, following USEPA test methods...

A data release containing information on macroinvertebrate communities and sediment toxicity in the Niagara River and adjacent areas collected during a sampling effort conducted between 2019 and 2020, and a sampling effort conducted in 2022. During the first sampling effort, bed sediments were collected at 60 sites in the Niagara River, 5 sites on lower Smoke Creek, and 6 sites on Hoyt Lake for use in sediment toxicity testing and determination of grain size distribution and total organic carbon concentration. Additionally, macroinvertebrate samples were collected from the 60 sites on the Niagara River. During the second sampling effort, bed sediments were collected at 10 sites on lower Smoke Creek (5 of which were...

In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program. One of the major goals of the NAWQA project is to determine how water-quality conditions change over time. To support that goal, long-term consistent and comparable monitoring has been conducted on streams and rivers throughout the Nation. Outside of the NAWQA project, the USGS and other Federal, State, and local agencies also have collected long-term water-quality data to support their own assessments of changing water-quality conditions. Data from these multiple sources have been combined to support...
