Data and code release—Comparative toxicity of emulsifiable concentrate and suspension concentrate formulations of 2′,5-dichloro-4′-nitrosalicylanilide ethanolamine salt

Bayluscide, the 2-aminoethanol salt of niclosamide (2′, 5-dichloro-4′-nitrosalicylanilide), is a pesticide that is used in conjunction with TFM (4-Nitro-3-(trifluoromethyl)phenol) to treat streams tributary to the Great Lakes that are infested with invasive parasitic sea lamprey (Petromyzon marinus). The application TFM with 0.5 to 2.0 percent (%) Bayluscide can significantly reduce the amount of

qPCR Results for An Assessment of Pathogens in National Park Hot Springs

In 2018 and 2019, a multidisciplinary team from the U.S. Geological Survey (USGS), National Park Service, The Commonwealth Scientific and Industrial Research Organization, Montana State University’s Department of Microbiology and Immunology, and the Teton Conservation District, initiated a study to document the presence or absence of Naegleria fowleri, Giardia, Escherichia coli, and Cryptosporidiu

Mercury Stable Isotope Assessment of Dragonflies and Fish Tissues across United States National Parks

This dataset details mercury (Hg) stable isotope values in dragonflies and fish tissues collected across U.S. National Parks. Dragonfly samples were collected as part of the Dragonfly Mercury Project (, a citizen science project focused on using dragonfly larvae as biosentinels for Hg bioaccumulation. Fish were collected as part of separate park-wide monitoring i

Abundance, Biomass, and Density Data for Fishes and Amphipods in Prairie Pothole Region Wetlands in 2019 and 2020

This dataset includes information from 59 prairie pothole wetlands in Minnesota, collected in 2019 and 2020. The data includes wetland characteristics (e.g., size, depth, plant biomass, and water quality), multiple fish metrics, and multiple amphipod metrics. The amphipod species include Gammarus lacustris and Hyalella azteca. There are 22 species of fish recorded.

Floodplain Inundation Model and Inundation Depths: Upper Mississippi and Illinois Rivers

Floodplain inundation is believed to be the dominant physical driver of an array of ecosystem patterns and processes in the Upper Mississippi River System (UMRS), which comprises the Upper Mississippi and Illinois Rivers. Here, we present a series of related data products supporting floodplain inundation modeling of the UMRS. First, raster files comprise a unique identifier, river mile positioning

Nutrient and sediment concentrations, loads, yields, and rainfall characteristics collected at a USGS subsurface-tile edge-of-field agricultural monitoring site in South Central Michigan within the Maumee River Basin, 2019-2023

This data release contains nutrient and sediment concentrations, loads, and yields from a USGS subsurface-tile edge-of-field (EOF) agricultural monitoring site. Sampling and flow monitoring were performed at the outlet of a subsurface-tile that drains 14.7 acres of cultivated cropland. The site is located in South Central Michigan and discharges into a headwater stream of the Maumee watershed. Thr

Model Archive for an Impulse Response Emulator of Groundwater Contaminant Transport Models

This archive contains the code and other files to demonstrate the creation and application of an impulse-response emulator for process-based groundwater flow and transport models in MODFLOW/MT3D. This includes creating a synthetic modeling environment in MODFLOW/MT3D, using PEST++ to derive an impulse-response (A) matrix (as described in White et al., 2020), using this A matrix to create a groundw

Sampling site, water quality, and fish community data from multi-agency monitoring of the Illinois Waterway response to lock and dam closures, 2019-2021

Lock and dam closures along the Illinois Waterway occurred in summer of 2020, resulting in a prolonged reduction in traffic of large vessels along the Waterway. To study the response of Illinois Waterway water quality and fish community, ongoing water quality and fish Long Term Resource Monitoring (LTRMP) elements of the Upper Mississippi River Restoration program were expanded from the La Grange

Microbial source tracking for streams in Scott County, Iowa, 2023

Surface water samples (n = 33) were collected in fall of 2023 at stream sites in Scott County Iowa, USA and were analyzed for microbial source tracking markers by quantitative polymerase chain reaction at the Laboratory for Infectious Disease and the Environment (LIDE). Microbial source tracking markers identify fecal sources of contamination by detecting microbes that are specific to certain anim

Otolith microchemistry for determining natal origins of prey fishes in the Upper Mississippi River System

This dataset includes otolith and water chemistry used for determining natal origins of individuals from six species. The dataset contains Sr:Ca and Ba:Ca of water samples for the Mississippi River and tributaries as well as otolith Sr, Ba, Mg values from fishes collected in navigation pools 4, 8, 13, and 26 of the Upper Mississippi River, as well as the Open River Reach of the Middle Mississippi

Data and code release: Acute toxicity of TFM to multiple life stages of Obovaria subrotunda, its host (Percina maculata), and a surrogate species (O. olivaria)

The risk of lampricide applications (such as 4-Nitro-3-(trifluoromethyl)phenol, TFM) to non-target fauna continues to be a concern within the Great Lakes Fishery Commission sea lamprey control program, especially among imperiled aquatic species—such as native freshwater mussels. The Grand River (Ohio) is routinely treated for larval sea lampreys (Petromyzon marinus) and this river contains populat

Python-HBRT model and groundwater levels used for estimating the static, shallow water table depth for the State of Wisconsin

A histrogram-based boosted regression tree (HBRT) method was used to predict the depth to the surficial aquifer water table (in feet) throughout the State of Wisconsin. This method used a combination of discrete groundwater levels from the U.S. Geological Survey National Water Information System, continuous groundwater levels from the National Groundwater Monitoring Network, the State of Wisconsin
