The establishment of an efficient aquifer water-quality aquifer monitoring network is a critical component in the assessment and protection of groundwater quality. A periodic evaluation of the monitoring network is mandatory to ensure effective data collection and possible redesigning of existing network. This package assesses the efficacy and appropriateness of an existing water-quality...

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.

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...

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.

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...

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...

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...

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...

To provide daily mean streamflow values at ungaged (partial-record) sites within the Yankee Fork Salmon River watershed, the U.S. Geological Survey (USGS), in cooperation with U.S. Bureau of Reclamation, used discharge measurements at three partial-record sites and related those measurements to a nearby USGS real-time streamgage (index site). Daily mean streamflow was estimated by...

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...

Discharge measurements and velocity mapping surveys were completed at select tie channels located at Nimz Ranch, on the main-stem Kootenai River. Tie channels convey water and sediments between the main river channel and river floodplain waterbodies. The velocity mapping surveys are used to document how the tie channels interact with the main-stem Kootenai River. Similar surveys will be...

In 2020, the Alaska Science Center and the Idaho Water Science Center conducted bathymetric surveys at three highway bridge structures. The bridge structures (NBI 331 and 1187) at Flag Point near Cordova, AK are located on Alaska State Route 10 (commonly referred to as the Copper River Highway). Bridge structure NBI 539 on the Knik River is located on the Old Glenn Hwy near Butte, AK...
