Characterizing Streamflow

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...

A synoptic study was conducted June 27-July 1, 2010 in the Muddy Creek drainage basin. The Muddy Creek drainage basin is in an area of energy develoment in south-central Wyoming. The synoptic study was integrated in nature and included the collection of water-quality, basin-sediment, and macroinvertebrate samples. Sampling sites were located on Muddy Creek from the headwaters area to near Baggs...

In cooperation with the Wyoming State Engineer, the USGS conducted a study of the water resources of Carbon County, Wyoming. This study followed the general plan of previous " County Studies". Surface water and ground water resources were evaluated through a combined approach that analyzed and summarized existing data and, as a consequence of the data analysis, identified key data gaps and...

In cooperation with the Wyoming State Engineer, the USGS conducted a study of the water resources of Sweetwater County, Wyoming. This study followed the general plan of previous " County Studies". Surface water and ground water resources were evaluated through a combined approach that analyzed and summarized existing data and, as a consequence of the data analysis, identified key data gaps and...

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...

The purpose of the crest-stage gage network is to inventory and monitor peak discharges throughout the state of Montana, with special emphasis on streams that may damage transportation infrastructure. Recorded data documenting peak streamflow at various sites within the state will be used by the Montana Department of Transportation to support assessments of culvert size, bridge construction, and...

Rivers and streams are constantly changing. Streamflows can change throughout the year and between years due to snowmelt, precipitation, diversions, and return flows. For many streams, these fluctuations determine whether a stream has year-round flow or not. PRObability of Streamflow PERmanence (PROSPER) is a project initiated to better understand what causes these fluctuations in different...
