Current Versus Historical Trends in Habitat Use by Wintering Raptors in the Snake River Birds of Prey National Conservation Area FY2011Research is showing that populations of wintering raptors, including Northern Harriers, Rough-Legged Hawks, Prairie Falcons, American Kestrels. Red-Tailed Hawks and Golden Eagles, have stayed relatively constant in the last 20 years are being used by the Bureau of Land Management and Idaho Army National Guard in developing raptor conservation management practices. The American Wind and WildlifeInstitute will also use the results for their wind energy siting support tools.

For example, exotic annual grass (EAG) invasion in western rangelands has increased wildfire frequency, which greatly reduces rangeland ecosystem diversity and leads to single-species dominance in many areas. Rangeland monocultures do not provide optimal carbon sequestration and other environmental processes necessary to sustain historically normal ecosystem structure, including the ecological diversity needed to support sagebrush obligates like Greater Sagegrouse, pygmy rabbit, and pronghorn. These obligates, as well as others, require contiguous,... Categories: Data; Tags: Bromus japonicus, Bromus tectorum, California (CA), Cheatgrass, Colorado (CO), All tags...

We used predictions of temperatures in streams across approximately two-thirds of the species' range in the U.S. to map coldwater streams or “patches” suitable for spawning and early rearing of Bull Trout. Each patch consists of streams with contiguous reaches of cold water. Patches were delineated using medium resolution National Hydrography Dataset streams containing modeled temperatures available at 1 km intervals, as provided by the NorWeST project (http://www.fs.fed.us/rm/boise/AWAE/projects/NorWeST.html).Once the...

The depth measurements included in this data release were obtained by wading the shallow channel margins and measuring the water depth directly on a top-setting wading rod used to collect flow velocity data with an acoustic Doppler velocimeter (ADV). For the deeper areas representing most of the channel, depths were recorded along a series of cross-sections by a SonTek RiverSurveyor M9 acoustic Doppler current profiler (ADCP) deployed from a kayak with the vertical beam of the...

Fish from this population are sampled as they pass Lower Granite Dam, but these sample data cannot be used directly to infer abundance because capture probability at Lower Granite Dam varies throughout the migration and because of the contemporaneous presence of unmarked hatchery-origin fish which are visually indistinguishable from natural-origin fish. Estimates of abundance were obtained by fitting a statistical mark-recapture model that integrated four related datasets: 1) the release/recapture data...

Reflectance measurements were made from a raft in the Swallow Bend reach of the Snake River using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in reflectance mode. The depth at each spectral measurement location was interpolated from field measurements of depth obtained with an acoustic Doppler current profiler. This data release provides both the reflectance spectra and the interpolated depths and can be used to develop relationships between depth and reflectance for mapping river bathymetry from field spectra or passive optical remotely sensed...

Based on the sampling locations, the sampled materials were presumed to have flowed through the dam turbines or over the spillway, thereby representing biological export from the reservoirs. Samples were collected biweekly at each location over a sixteen-month period, June 2018 – September 2019. Sampling and analysis methods are described in the Processing Steps section of the metadata.

The model archive summary describes the methods and techniques used to develop the model for the Snake River at Weiser, ID – USGS site ID# 13269000. The model can be used to develop a time series of suspended sediment concentration based on acoustic backscatter and tributary flow data to determine the suspended sediment concentration at the site in real-time. The suspended sediment time series will help enable science entities, managers, and others, track the movement of sediment in the Snake River above Brownlee Reservoir.

Due to concerns regarding mercury (Hg) contamination within the HCC, in cooperation with Idaho Power Company, the U.S. Geological Survey has been leading an investigation into the sources, transport, microbial transformations, chemical speciation and bioaccumulation of Hg in this complex river-reservoir environment. This data release is focused on the sediment component of this larger effort and includes data collected between 2014 and 2018 from shallow surface sediment (≤ top 5 cm) and from sectioned...

Water samples were collected from 21 tributary sites representing a range of watershed land use types (e.g., agriculture, forest, etc.) within the Snake River Basin. In 2018, water samples were collected at tributary sites near the confluence of the Snake River and at sites upstream higher in the watershed. In the 2019 and 2020, the tributary water sample collection was focused on downstream sites near the Snake River. In addition, from 2015-2018 Hg stable isotopes were also measured in air, bed sediment, and geologic material from...
