Physical and Hydraulic Monitoring on the Yellowstone River Fish Bypass Channel, Montana, May 2022 to August 2023

This data release was produced by the U.S. Geological Survey (USGS) in cooperation with the Bureau of Reclamation to present the results of monitoring efforts on the Yellowstone River fish bypass channel according to the specifications of the Lower Yellowstone Adaptive Management and Monitoring Plan. The fish bypass channel was constructed to provide upstream migrating fish with a route around a d

Digitized datasets used in channel stability study in the Colorado River headwater arroyo system of Muddy Creek, Wyoming

A before-and-after study design was used to examine effects of changes in cattle grazing practices on channel stability in Muddy Creek, an arroyo in the Colorado River headwaters. The changes in grazing practices were abrupt and focused on keeping cattle out of the riparian zone and increasing herd movement. We digitized 620 meander loop cutoff geometries within the digitized alluvial valley botto

Water-Quality, Bed-Sediment, and Invertebrate Tissue Trace-Element Concentrations for the Clark Fork River and Tributaries in the Upper Clark Fork Basin, Montana, October 2020-September 2021

Water, bed sediment, and invertebrate tissue were sampled in streams from Butte to near Missoula, Montana (MT), as part of a long-term monitoring program within the Upper Clark Fork Basin. The sampling program was completed by the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the Upper Clark Fork Basin and monitor trace e

Peak-flow frequency analyses for selected streamgages in the Upper Yellowstone River Basin, based on data through water year 2022

The USGS Wyoming-Montana Water Science Center (WY–MT WSC) completed a report (Sando and McCarthy, 2018) documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines. The methods are used to provide estimates of peak-flow quantiles for 66.7-, 50-, 42.9-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs) for selected US

Channel geometry for upstream and downstream cross sections at selected bridge sites in Montana, 2022

The U.S. Geological Survey, in cooperation with the Montana Department of Transportation (MDT), collected cross-section data on the upstream and downstream sides at 18 sites involving 20 bridges in Montana during the 2022 calendar year. The purpose of the data collection is to determine if scour and channel instability occur in the vicinity of the bridge structures. Data were processed, analyzed,

Input Files and WRTDS Model Output for the two major tributaries of Lake Koocanusa

Canadian discrete water quality data and daily streamflow records were evaluated using the Weighted Regression on Time, Discharge, and Seasons (WRTDS) model implemented with the EGRET R package (Hirsch et al. 2010, Hirsch and De Cicco 2015). Models were used to estimate loads of solutes and evaluate trends for three constituents of interest (selenium, nitrogen, and sulfate). Six models were genera
