The U.S. Geological Survey, in cooperation with the Montana Department of Transportation, installed cameras and large-scale particle image velocimetry (LSPIV) recording equipment at four sites where the U.S. Geological Survey and Montana Department of Transportation are monitoring bridge scour using other methods. Determination of stream velocities is an important component of hydraulic engineerin
Selenium in the Kootenai River Basin, Montana and Idaho, United States, and British Columbia, Canada
Selenium entering the 90-mile long transboundary Koocanusa Reservoir (also called Lake Koocanusa) in southeastern British Columbia, Canada, and northwestern Montana, United States, has been measured at concentrations above State and Federal water-quality and aquatic life standards. The reservoir is within the international Kootenai (or “Kootenay” in Canada) drainage basin, which contains critical
Methanogenic archaea in subsurface coal seams are biogeographically distinct: An analysis of metagenomically-derived mcrA sequences
The production of methane as an end-product of organic matter degradation in the absence of other terminal electron acceptors is common, and has often been studied in environments such as animal guts, soils, and wetlands due to its potency as a greenhouse gas. To date however, the study of the biogeographic distribution of methanogens across coal seam environments has been minimal. Here, we show t

Developing CE-QUAL-W2 Models of the Kootenai River and Koocanusa Reservoir, Montana and Idaho
The construction and operation of Libby Dam, a U.S. Army Corps of Engineers (USACE) project located in northwestern Montana, has altered the natural hydrograph, thermal regime, sediment transport, and nutrient loadings on the Kootenai River. Dam operation impacts riverine ecosystem function and many fish species, including the federally endangered Kootenai River White Sturgeon and federally...
History of Water-Quality Sampling the the Lake Koocanusa Basin
Since 1984, Canadian agencies have collected samples to measure selenium concentrations in the Elk River measured at the monitoring station (site BC08NK0003) (British Columbia Ministry of Forests Lands Natural Resource Operations and Rural Development, 2022) which is 2.2 miles above its discharge into Lake Koocanusa. Detections of selenium from this site have ranged from below detection to greater...
