WRTDS annual concentrations, loads and statistical trend likelihoods for sites in the Spokane River watershed, water years 1990-2018 WRTDS annual concentrations, loads and statistical trend likelihoods for sites in the Spokane River watershed, water years 1990-2018
A long history of mining and widespread metals contamination in the Spokane River watershed have led to the area's designation as a Superfund site and extensive, ongoing remedial actions. Long-term (water years 1990 to 2018) water-quality data from twelve sites were used to develop Weighted Regressions on Time, Discharge and Season (WRTDS) and WRTDS with Kalman filtering (WRTDS_K) models...
Chemical characterization of water and suspended sediment of the Snake River and Hells Canyon Complex (Idaho, Oregon) (ver. 3.0, November 2023) Chemical characterization of water and suspended sediment of the Snake River and Hells Canyon Complex (Idaho, Oregon) (ver. 3.0, November 2023)
This dataset includes laboratory analyses of surface water samples and sediment trap material collected from (1) locations upstream, downstream, and within the Hells Canyon Complex (Idaho, Oregon) of the Snake River, (2) tributaries of the Snake River, and (3) two reservoirs near Boise, Idaho, from 2014 to 2021. The study area spans approximately 232 river miles of the Snake River and...
WildAgg: an R package to estimate and visualize wildlife aggregation data WildAgg: an R package to estimate and visualize wildlife aggregation data
This package is designed to estimate, summarize, and visualize wildlife aggregation metrics using location information like GPS collar data. The motivation for the development of this package began with two research efforts studying the aggregation and density of elk on the National Elk Refuge, Wyoming (Janousek et al.2021; and Graves et al. 2021). The primary goal of the WildAgg package...
Geospatial Data for Bridge Scour Countermeasure Assessments at Select Bridges in the United States, 2016-18 Geospatial Data for Bridge Scour Countermeasure Assessments at Select Bridges in the United States, 2016-18
In 2009, the Federal Highway Administration published Hydraulic Engineering Circular No. 23 (HEC-23) to provide specific design and implementation guidelines for bridge scour and stream instability countermeasures. However, the effectiveness of countermeasures implemented over the past decade following those guidelines has not been evaluated. Therefore, in 2013, the U.S. Geological...

This data release and accompanying spreadsheet illustrate the ecosystem scale selenium model for Lake Koocanusa described in USGS Open-File Report 2020-1098, "Understanding and Documenting the Scientific Basis of Selenium Ecological Protection in Support of Site-Specific Guidelines Development for Lake Koocanusa, Montana, U.S.A., and British Columbia, Canada." All report sections...
Water use by source and category in Idaho counties, 2015 Water use by source and category in Idaho counties, 2015
Water Use by Source and Category in Idaho Counties are compiled as part of the "Estimated Use of Water in the United States" series of U.S. Geological Survey Circular reports that have been published every 5 years since 1950 (Maupin and others, 2014). Idaho withdrawals in 2015 are being published as a separate dataset in support of the U.S. Geological Survey fact sheet 2018-3036. Maupin...
