Streamflow regressions and daily mean streamflow estimates for Kootenai River tributaries near Bonners Ferry, Idaho

The U.S. Geological Survey (USGS), in cooperation with the Kootenai Tribe of Idaho, used streamflow measurements at 14 partial-record sites and related them to nearby USGS real-time streamgages (index sites) to provide daily mean streamflow values at ungaged (partial-record) sites. Daily mean streamflow was estimated by developing a regression relationship between streamflow at each partial-record

Kootenai River Habitat Restoration Project Bathymetric Surveys near Bonners Ferry, ID, Water Years 2012-2021

In 2009, the Kootenai Tribe of Idaho released and implemented the Kootenai River Habitat Restoration Master Plan. This plan aimed to restore, enhance, and maintain the Kootenai River habitat and landscape to support and sustain habitat conditions for aquatic species and animal populations. In support of these restoration efforts, the U.S. Geological Survey, in cooperation with the Kootenai Tribe o

Hydrogeologic Framework of the Big Lost River Basin, South-Central Idaho: Hydrogeologic Framework Model and Well Data

Groundwater in the Big Lost River Basin is vital to irrigated agriculture in the basin and water users are concerned about declining groundwater levels. The U.S. Geological Survey, in cooperation with the Idaho Department of Water Resources, developed a hydrogeologic framework to provide a conceptual understanding of groundwater resources in the Big Lost River Basin. A three-dimensional hydrogeolo

U.S. Geological Survey and U.S. Army Corps of Engineers Bathymetric Survey of Lake Koocanusa, Lincoln County, Montana, 2016-2018

In 2016, the U.S. Army Corps of Engineers (USACE) started collecting high-resolution multibeam echosounder (MBES) data on Lake Koocanusa. The survey originated near the International Boundary (River Mile (RM) 271.0) and extended down the reservoir, hereinafter referred to as downstream, about 1.4 miles downstream of the Montana 37 Highway Bridge near Boulder Creek (about RM 253). USACE continued t

Potentially Resolvable National Hydrography Dataset Waterbodies and Flowlines from Landsat Images in the United States (excluding Alaska)

This data release presents two datasets including waterbodies (reservoirs, lakes, ponds, wetlands, etc.) and flowlines (stream reaches) from the high-resolution National Hydrography Dataset Plus (NHDPlus HR) that are potentially observable from Landsat images for the United States (excluding Alaska). To determine where National Hydrography Dataset Plus high resolution (NHDPlus HR; USGS 2019) featu

Mores Creek Arm Bathymetric Survey, Lucky Peak Lake, Boise County, Idaho, May 11 - 13, 2021

In 2004, about 90 migrating elk drowned after attempting to cross thin ice on the Mores Creek arm of Lucky Peak Lake upstream of the Highway 21 bridge. To better understand the depths over a range of reservoir pool elevations in the Mores Creek Arm, the U.S. Geological Survey, in cooperation with the Lucky Peak Power Plant Project, conducted high-resolution multibeam echosounder (MBES) bathymetric

Sensitivity and precision of stream permanence estimates (1977-2019) from the USGS Thornthwaite Monthly Water Balance Model in the Pacific Northwest, USA

This dataset includes inputs and results for parameterizing the USGS Thornthwaite Monthly Water Balance Model (MWBM) to simulate annual stream permanence on National Hydrography Dataset (NHD) stream reaches. Also included are results from sensitivity analysis of MWBM parameters to final stream permanence classification (permanent or nonpermanent). The dataset includes files that link PRISM climate

Measurements of Discharge in Small, Low-Flowing Streams Using Multiple Techniques

The accompanying datasets include all field measurements collected as part of a study to evaluate multiple streamflow measurement techniques in small streams throughout the United States. Each individual dataset is paired with a metadata record describing the contents and purpose of that dataset.

Nutrient limitation of algae and duckweed in streams: data from laboratory bioassays and field experiments

Data supporting the article, "Nutrient limitation of benthic algae in streams: integrating laboratory bioassays, field experiments, and field data." Datasets include from a battery of laboratory and in situ nutrient limitation tests in streams in the upper Snake River basin, Idaho. Nutrient limitation bioassays of stream water used the green algae Pseudokirchneriella subcapitata (formerl

Water budget components for hydrologic regions and tribal lands: annual averages 1971-2000

Water budget components for 17 hydrologic regions of the United States which contain tribal lands and for the tribal lands within each of these regions. All values represent an average year based upon the years 1971-2000, and are the result of a combined analysis of national datasets.

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 for total

Chemical characterization of water and suspended sediment of the Snake River and Hells Canyon Complex (Idaho, Oregon)

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 2019. The study area spans approximately 232 river miles of the Snake River and includes: si
