Note: This data release is currently being revised and is temporarily unavailable. Two types of passive samplers for polychlorinated biphenyl (PCB) analysis were deployed in the Clinton River Area of Concern in 2019: semipermeable membrane devices for water and in-stream sediment samplers. Samplers were deployed in July 2019 and retrieved in August 2019. Additionally, bank sediment samples for PCB analysis were collected by the U.S. Geological Survey (USGS) in August 2019 and catch basin bottom material samples for PCB analysis were collected by LimnoTech in November 2019 under contract with the U.S. Army Corps of Engineers. These data are a part of a larger study and associated USGS report (https://doi.org/TBD).

This data release contains cyanotoxin, chlorophyll-a, and pheophytin-a concentration, cyanobacterial genetics, phytoplankton community composition, and multiparameter sonde data collected from 20 sites in five northeastern United States river basins (Penobscot (ME), Santuit (MA), York (VA-WV), Salem (NJ), and Peconic (NY)). Solid Phase Adsorption Toxin Tracking (SPATT) passive samplers were deployed at all sites between August 31 and September 2, 2020, and retrieved after 7 days. Discrete water samples were collected when SPATTs were deployed, and at 2 sites (USGS station IDs 01670257, 0167014792), samples were also collected when the SPATTs were recovered. Sonde data were collected when deploying and retrieving...

In 2004, 2007, 2010, and 2013, the U.S. Geological Survey sampled benthic algae and invertebrates, and fish to assess the condition of the aquatic communities and water quality in 14 wadable streams near Milwaukee, Wisconsin. Additional community sampling was also done at a subset of three sites in 2011 and 2012 to assess temporal variation. Selected environmental (physical and chemical) data in the streams were collected to evaluate potential relations to the biota and the ecological health of the streams. Physical and chemical data included land-use/land cover; streamflow from USGS gages (except at two creeks that were not gaged); stream habitat; microhabitat at invertebrate collection points (depth, velocity,...

Streambed sediment samples were collected in October 2016 from streams tributary to Wisconsin’s western Lake Michigan shoreline. Streams included two Areas of Concern (AOCs), two non-AOC comparisons, and two additional non-AOC study areas. Within the Milwaukee Estuary AOC, samples were collected from the Milwaukee River (three subsites), the Menomonee River (two subsites), the Kinnickinnic River (2 subsites), and the Milwaukee Harbor (one subsite). The Milwaukee, Menomonee, and Kinnickinnic Rivers converge in the Milwaukee Harbor and then discharge to Lake Michigan. Within the Sheboygan River AOC, samples were collected at three subsites. Samples were also collected at two subsites in the Manitowoc River and two...

This data release provides phytoplankton identification, phytoplankton enumeration, chlorophyll concentration, phaeophytin concentration, phycocyanin data, and nutrient quality assurance data from three recurring algal bloom sites in Kabetogama Lake, Voyaguers National Park, Minnesota in 2016 and 2017. The goal of this research is to better understand the drivers of algal bloom toxicity in the large lakes of Voyageurs National Park so that resource managers may better predict, manage, and mitigate the occurrence of harmful algal blooms. A total of 126 environmental samples were collected at three recreational areas where blooms frequently occur. One site, Sullivan Bay, was chosen for more intensive sampling, including...
5-day composite river water samples were collected from two sites: Menomonee River (U.S. Geological Survey station number 04087142) and Underwood Creek (U.S. Geological Survey station number 04087088) in Milwaukee, Wisconsin. 5-day composite wastewater (raw sewage) influent samples were also collected from the Jones Island Water Reclamation Facility (U.S. Geological Survey station number 430125087540400). 5-day composite samples were collected from 2017 to 2019. Grab samples and time-series data (one-hour streamflow and 10-minute optical sensor measurements) were also collected from the Menomonee River (U.S. Geological Survey station number 04087142) site from 2017 to 2018, which are presented in this data release....

Aquatic ecological surveys are valuable to understanding the interaction between the biotic and abiotic components in rivers and streams. However, large-scale assessments of the water chemistry, geomorphology, and ecological community are usually not feasible due to limited resources. Beginning in 2013, the Regional Stream Quality Assessment Project of the US Geological Survey’s National Water Quality Program, began sampling 89-120 streams in each of 5 regions across the conterminous United States—the Midwest (2013), Southeast (2014), Pacific Northwest (2015), Northeast (2016), and California (2017). Sampling included water and streambed sediment chemistry, stage and temperature (Journey and others, 2015). The abiotic...
Algal toxins are a growing concern worldwide. Rapid assessment test strips are a newer technology and their accuracy in detecting toxins in different lakes with different phytoplankton and toxins present is unknown. This data release is supported by our testing of toxin test strips. This research took place in Voyageurs National Park in northern Minnesota. The research will indicate whether these test strips are accurate for this system, and hopefully lay the foundation for a cost-effective harmful algal blooms (HABs) monitoring and communication tool for Voyageurs National Park and other parks. The utility of the test strips in this system may lead to broader applications, for instance in other inland systems like...
Data are for zooplankton communities sampled in 2016 at the Sheboygan River Area of Concern and two comparison sites, the Kewaunee River and the Manitowoc River, which have similar physical and chemical characteristics. Zooplankton were collected by using tows from depth to the surface with a 63 micrometer mesh plankton net. Physical and chemical data that were sampled concurrently (specific conductance, temperature, pH, and dissolved oxygen) in water by use of a multi-parameter water-quality sonde, and the results of field quality assurance quality control are also included.
