Tongue River Surface-Water-Quality Monitoring Network

Coal-bed methane development is in the initial stages of exploration and production in the Tongue River watershed. Long-term monitoring is needed to provide information to evaluate any changes or trends in surface-water quality and support informed decisions about resource use and management. The goals of this monitoring program are to collect water-quality data and disseminate...

Assessment of Aquatic Communities in Northeastern Wyoming and Southeastern Montana

The Powder River Structural Basin (PRB) in northeastern Wyoming and southeastern Montana is an important source of energy resources for the United States. Resources developed from the basin include coal, oil, uranium, conventional natural gas, and within the last decade coal-bed natural gas (CBNG) which often is referred to as coal-bed methane. As of 2008, about 20,000 CBNG wells had been...

Development of Regional Curves Relating Bankfull-Channel Geometry and Discharge to Drainage Area for Hydrophysiographic Regions in Wyoming

The Watershed Program in cooperation with the U.S. Geological Survey (USGS), Wyoming Water Science Center developed regional curves that relate bankfull channel dimensions and discharge to drainage area for hydrophysiographic regions in Wyoming where data are currently lacking. Regional curves are useful aids for estimating bankfull discharge and related channel dimensions at ungaged sites,...

Streamflow Statistics for Unregulated and Regulated Conditions for Selected Locations on the Yellowstone, Tongue, Powder, and Bighorn Rivers, Montana

Major floods in 1996-1997 on the Yellowstone River intensified public debate over the effects of human activities on the Yellowstone River. The Yellowstone River Conservation District Council partnered with the U.S. Army Corps of Engineers to conduct a cumulative-effects study on the Yellowstone. For that study, the USGS calculated streamflow statistics for unregulated (no development) and...
