A comparison of non-contact methods for measuring turbidity in the Colorado River A comparison of non-contact methods for measuring turbidity in the Colorado River
Monitoring suspended-sediment concentration (SSC) is essential to better understand how sediment transport could adversely affect water availability for human communities and ecosystems. Aquatic remote sensing methods are increasingly utilized to estimate SSC and turbidity in rivers; however, an evaluation of their quantitative performance is limited. This study evaluates the performance...
Water withdrawal and consumption trends for thermoelectric-power plants in the conterminous United States, 2008-2020 Water withdrawal and consumption trends for thermoelectric-power plants in the conterminous United States, 2008-2020
Freshwater-using utility-scale thermoelectric (TE) plant water-use estimates were evaluated for annual trends from 2008 to 2020 across the conterminous United States (CONUS) and within hydrologic regions. Overall, TE water withdrawal and consumption trends declined across CONUS by 14,335 and 278 million liters/day, respectively. Decreasing water withdrawal and consumption trends for TE...
Effects of restoration work on Kootenai River Acipenser transmontanus (white sturgeon) critical habitat, Kootenai River, northern Idaho, 2011–22 Effects of restoration work on Kootenai River Acipenser transmontanus (white sturgeon) critical habitat, Kootenai River, northern Idaho, 2011–22
Between 2011 and 2018, the Kootenai River Habitat Restoration Project, led by the Kootenai Tribe of Idaho, implemented restoration treatments to enhance the natural recruitment of the critically endangered Acipenser transmontanus (white sturgeon) and other fish native to the Kootenai River. These restoration treatments in the Straight and Braided Reaches of the Kootenai River are...

Mercury Cycling in the Hells Canyon Complex
The Hells Canyon Complex (HCC) is the largest privately owned hydroelectric power complex in the United States. Upstream are millions of acres of irrigated agricultural lands and Idaho’s largest metropolitan area clustered around the state capital Boise. Downstream lie confluences with the Salmon and Clearwater Rivers, critical habitat for threatened bull trout and fall chinook salmon. Elevated...
Real-Time Pier Scour Monitoring and Evaluation
The most common cause of bridge failure is scour, when high-velocity streamflow scours streambed material from around bridge piers and abutments. As of 2017, the National Bridge Inventory listed 265 of Idaho's nearly 4,500 bridges (about 6 percent) as "scour critical." When rivers rise quickly, bridge inspectors have little or no time to mobilize and monitor bridges at risk of scour. Real-time...
