As stream temperatures increase, cold water adapted brook trout populations are projected to decline. However, there are mechanisms brook trout can use to persist in warming streams. Those mechanisms include acclimation, adaptation, and utilizing cold water refugia in streams where thermal heterogeneity is high. Using implanted temperature recording tags, this study examines individual...

Images of the seafloor off the Kona coast of the Island of Hawai`i were collected by the United States Geological Survey in 2003, 2004, and 2022, during field activities A803HW, A204HW, A604HW, and 2022-615-FA. The images were acquired in cooperation with the National Park Service, primarily in the waters off Kaloko-Honokohau National Historical Park, Pu`ukohola Heiau National Historic...

Underwater measurements of photosynthetically active radiation were collected along multiple transects throughout Lake Michigan during the 2021 cooperative science monitoring initiative survey of the lake. These data were collected as part of an effort to quantify the water transparency of the lake. The data included in this release provide the percent of photosynthetically active...

This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 5 and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations and seasonal ranges. This data release provides the means for ungulate migrations to be mapped and...

This data set contains harvest regulations and annual harvest for antlerless white-tailed deer in 8 Midwestern US states. The data includes harvest regulations for each unit and year as well as the annual harvest for antlerless white-tailed deer by firearm or during a modern firearm season depending on individual state record keeping. Spatial change of support has been applied to unify...

This dataset contains the accumulated stream survey data collected to identify climate impacts to fish communities and assess stream restoration as a potential climate-change mitigation action across the Great Plains and High Desert of Wyoming and Montana (2021-2024). We also provide data of incidental observations of amphibians, reptiles, crayfishes, and mussels seen while conducting...

We tested 28 fin clips for DNA of Goldfish (Carassius auratus) and Prussian Carp (Carassius gibelio) following published assay methods. Results are reported as cycle threshold (Cq) values generated using real-time PCR.

These data along with continuous monitoring at several locations (data provided through NWIS) are used to monitor bottom salinity and tidal currents associated with a project to better monitor X2 (position of 2 PSU [Practical Salinity Units] isohaline) in the lower Sacramento River and Suisun Bay, CA. Links to NWIS sites are provided in the associated web links under 'Related External...

A wastewater reuse model was applied to the Upper Colorado River basin to assess the (1) percent of accumulated wastewater (ACCWW%) from municipal and industrial wastewater treatment plants (WWTPs) in each initialized (that is, has an assigned hydrosequence number for flow-routing) National Hydrography Dataset Version 2.1 (NHDPlus V2.1) stream segment; and (2) predicted environmental

Salinity levels in streams and tributaries of the Colorado River Basin have been a major concern for years. Recently, the United States Geological Survey’s (USGS) Next Generation Water Observing System (NGWOS) program expanded stream monitoring networks including the number of sites where continuous (15-minute) specific conductance is measured in the Colorado River Headwaters and...

Note: This data release has been deprecated. Please see new data release here: https://doi.org/10.5066/P138MUCW. This data release includes downscaled climate inputs and hydrologic outputs from the Basin Characterization Model (BCM) version 8 (v8), described in Flint et al. (2021a), in a 30 by 30-meter spatial resolution at a monthly time step from water years 1896 to 2023 for the upper...

A systematic sampling design was developed to sample mussels in Upper Mississippi River navigation pools 3, 5, 6, 8, 13 and 18. Hydrologically-enforced buffers were created at a hierarchy of scales to better determine the extent of influence on mussel population assemblages. Buffers were generated using a radii of 10, 100, 500 and 1,000 meters from the quadrat site point. Several...
