Daily temperature predictions in the Delaware River Basin (DRB) can inform decision makers who can use cold-water reservoir releases to maintain thermal habitat for sensitive fish and mussel species. This data release supports a variety of flow and water temperature modeling efforts and provides the inputs and outputs of both machine learning and process-based modeling methods across 456 river rea

Big Oaks National Wildlife Refuge (NWR) is a 50,000 acre refuge overlaid on portions of the former Jefferson Proving Ground (JPG) in Jefferson, Jennings, and Ripley counties, Indiana. Beginning in 1996, the U.S. Fish and Wildlife Service (USFWS) began managing the area. Big Oaks NWR was established in June 2000 as an “overlay” Refuge through a 25-year real estate permit from the U.S. Army. As an o

The Corps of Engineers' Rock Island District is planning an unprecedented closure of the Illinois Waterway in 2020 in order to perform required maintenance on locks. Aerial imagery will document river conditions prior to the closure (2019) and after the locks are reopened (2021). Under a separate but related effort, aerial imagery of the entire Illinois Waterway will be collected in 2020 as part o

These data were collected as part of a study headwater streams of the lowland Brazilian Amazon to assess the effects of land use change on organic matter dynamics (OM), ecosystem metabolism, and nutrient concentrations and uptake (nitrate and phosphate) in 11 first order streams draining forested (n=4) or cropland (n=7) water-sheds with intact riparian forests. Data included here are from 10 strea

In this data release, we provide data to describe the water quality in Green Lake, Wisconsin, from 1905 to 2020, primarily the constituents for which it is impaired, including near-surface total phosphorus concentrations and metalimnetic dissolved oxygen concentrations, and quantify the water and phosphorus inputs to the lake. We also provide inputs to and outputs from the General Lake Model coupl

This model archive contains model files and a complete repeatable workflow for source water delineation for groundwater supply wells in the Neversink/Rondout Basins of New York. The U.S. Geological Survey, in cooperation with the NYSDEC and NYSDOH, began an investigation in 2019 with the general objectives of (1) improving understanding of the regional groundwater flow system (2) delineating areas

Zequanox® is an EPA-registered biopesticide for controlling populations of dreissenid mussels (zebra and quagga mussels). Zequanox has demonstrated selective toxicity toward dreissenid mussels; however, a recent laboratory study indicated the potential for Zequanox to impact a non-target salmonid species. We assessed the potential exposure risk by observing the avoidance behavior of two representa

This dataset captures the Zebra Mussel dose-response to four independent toxicants and each binary mixture of those toxicants. Toxicants included EarthTec QZ, Clam-Trol CT-2 (syn. Spectrus CT1300), niclosamide, and potassium chloride. Each dose of toxicant was verified with either ICP-OES or UHPLC, depending on analyte, and comparison to a standard curve. Mortality was tabulated for each observati

In 2016, for the first time, an abundance of age-0 silver carp (Hypophthalmichthys molitrix) were captured at several sites upstream of Lock and Dam 19 on the Upper Mississippi River near Keokuk, Iowa. These data were collected in an attempt to determine the early life environments and frequency and timing of the reproductive events that led to a large year class of age-0 silver carp. This info

These data tables summarize land cover classifications, slope measurements, and inundated area estimates for several lakes in northern Minnesota, as part of a larger project seeking to identify associations between young-of-year Yellow Perch mercury content and water level metrics, temperature, and annual deposition data in a multivariate analysis. One table presents inundated area estimates for a

A high-resolution sidescan image of the Mississippi River, Lock and Dam 19 approach (downstream) was collected with a Humminbird Solix. Side-imaging sonar creates an image of underwater riverbed features by measuring the intensity of acoustic reflections. This mega side-imaging sonar data was collected and mosaicked to capture more detailed information on the condition of the lock approach to prov

Acoustic telemetry data (Vemco, Inc) were collected on invasive silver carp (Hypophthalmichthys molitrix), bighead carp (H. nobilis) and their hybrids in the upper Mississippi River (navigation pools 15-19) to determine movement patterns and preferred habitats during September 2013 through November 2017. We consolidated these data into intervals of fish within-pool residency and intervals of fish
