The headwaters of the Snake River are in the mountains of northwestern Wyoming on lands primarily administered by the National Park Service and the Bridger-Teton National Forest. Streamflow from the Snake River Basin has been measured at some sites for more than 100 years. Water from this drainage basin is used for recreational, agricultural, and municipal uses and power generation. Because of the
Evaluating the use of video cameras to estimate bridge scour potential at four bridges in southwestern Montana
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
Controlling skewness in MOVE3 peak-flow record extensions
Streamgage record extension methods such as the maintenance of variance Type 3 (MOVE3) method improve flood frequency estimates at a target streamgage by incorporating information from a nearby, hydrologically similar index streamgage. Bulletin 17C recommends using a variation of the MOVE3 method to estimate values at the target streamgage for only a subset of the available data at the index strea

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...
