These data were compiled for/to modeling efforts for U.S. Bureau of Reclamation National Environmental Policy Act (NEPA) analyses for the Colorado River in Grand Canyon, Arizona. Objective(s) of our study were to create revised monthly Lake Powell elevations and outflows from Bureau of Reclamation Colorado River Mid-term Modeling System (CRMMS) traces that incorporate the alternatives in the sEIS documents and indicate when potential actions may occur and how that changes water movement and storage. These data represent monthly hydrologies for Lake Powell: inflow, outflow, and elevation forecasts for 2024-2027, as well as volumes of water in outflows for different water mangement strategies in NEPA supplemental...
Hydroacoustic estimates of fish density are used for fisheries management in central Lake Erie. Hydroacoustic data were collected along up to four cross-lake transects in central Lake Erie July 2010 through July 2019. Software-generated raw variables used for calculating estimates of hydroacoustic fish densities are presented here.

This USGS data release documents species distribution models for 271 fluvial fish species in their native ranges of the conterminous United States. Source data, supporting code and model results are documented in this data package. Boosted Regression Tree (BRT) models were used to develop presence/absence predictions for each of the National Hydrography Dataset Plus Version 2.1 stream segments within a species' native range. The predictions provided can be linked to the NHDPlusV2.1 geospatial dataset through the COMID to create a spatial depiction of the models. The primary results are stored in the file "BRT Predictions" and are provided in comma separated value (CSV) and Parquet file formats. Parquet file format...

This dataset records Cladophora and associated submerged aquatic vegetation (SAV) biomass collected approximately monthly during the growing season of 2019 at stations located along the U.S. shoreline of Lakes Michigan, Huron, Erie, and Ontario. It also records a variety of supporting data collected at Cladophora measurement stations. These supporting data include: - seasonal time series of light, currents, wave action, temperature, specific conductivity, turbidity, pH, phycocyanin, chlorophyll, and dissolved oxygen from moored sensors at a subset of stations; - measurements of Secchi disk depth and water chemistry; - water column profiles of temperature, specific conductivity, turbidity, pH, phycocyanin, chlorophyll,...

Invertebrate, fish, and habitat data were collected as part of a cooperative project that began in 2002 between the U.S. Geological Survey, Colorado Springs Utilities, and Colorado Springs Engineering. Other entities have contributed to the project over the years including Colorado Parks and Wildlife. Habitat samples were collected and analyzed at 27 sites – 25 in the Fountain Creek Basin as well as two sites on the Arkansas River, El Paso and Pueblo Counties, Colorado. The number of sites sampled each year as well as the number of annual visits during which data were collected, and sampling methods used during each visit vary. The habitat data were collected between 2002 and 2023 and is intended to be updated annually...

A total of 236 Black Carp were collected throughout the year from 2017-2019 by incidental captures of commercial fishers and biologists. Capture date, river basin of capture location, and coordinates were recorded for each Black Carp captured. A subsample of 119 Black Carp varying from 429-1268 millimeters total length were compared for the precision of annuli counts by two experienced readers for the ossified two anterior pectoral fin rays, the ossified anterior dorsal fin ray, sectioned vertebrae, and lapilli otoliths for selection of a single structure based on percent exact agreement, coefficient of variation, and age-frequency plots.

Datasets include invertebrate frequency of occurrence, invertebrate tolerance index values, invertebrate multi-metric index, and new zealand mudsnial counts. Description of invertebrate sampling methodology are documented in the associated publication (https://doi.org/10.5066/P9PUY4FC).

These two datasets contain metrics from hydrodynamic and particle tracking simulations for two sub-reaches of the Upper Missouri River near Wolf Point, MT. The upstream reach is referred to as the “upper” reach while the downstream reach is referred to as the “lower” reach. Simulations were performed for 16 flows in the range of 185-635 cms at increments of 30 cms.

This dataset provides the estimated cell abundance and total biovolume for whole-water picoplankton samples collected by the U.S. Geological Survey (USGS) at 25 different sites in Kansas between August of 2020 and August of 2022. The samples were analyzed by BSA Environmental Services, Inc. This data is part of a larger multi-agency project between U.S. Environmental Protection Agency, National Aeronautics and Space Administration, National Oceanic and Atmospheric Administration, and USGS called the Cyanobacteria Assessment Network (CyAN). The goal of the CyAN project is to develop a satellite-based, early warning system to detect harmful algal blooms (HABs) in freshwater systems.

Lake Erie walleye (Stizostedion vitreum) recruitment fluctuates annually and depends partially on their diet and growth during their first year of life. To determine how age-0 walleye have responded to changes in prey species and abundance, larval and young of year walleye were collected from western Lake Erie in 2019 and 2014. Larval and young of year fish stomachs were extracted and dissected, with prey contents removed for later identification. All prey contents were identified to the lowest possible taxonomic level using a dissecting microscope and counted, with up to 20 prey items from each taxa per fish measured (0.01 mm) using a digital computer image analysis system. Zooplankton prey items were identified...

Since 2005, the U.S. Geological Survey - Great Lakes Science Center's Lake Erie Biological Station (LEBS) has participated in a collaborative, multiagency effort to assess pelagic prey fish populations in the western (WB), central (CB), and eastern (EB) basins of Lake Erie through a combination of hydroacoustic and midwater trawl sampling. Assessing lake-wide distribution and abundance of pelagic prey species over time facilitates evaluation of large-scale drivers of fish production while also considering food-web dynamics at a smaller sub-basin scale. Information from this survey will support decision making within an ecosystem-based fishery management framework. In support of binational Great Lakes fishery management,...
