Cheyenne River Field Work Description

A list of 50 site locations was developed with sites being preferentially located where United States Geologial Survey (USGS) gages are currently located or have previously been located. Stream assessments have previously been performed above Angostura Reservoir, in the upper portions of Spring Creek Watershed, in Rapid Creek Watershed, and in Belle Fourche River Watershed. Additional sites in these areas were limited. Data from the previous work will augment the characterization of the stream physical habitat throughout the entire watershed.

The stream channel at each of the chosen sites was classified using South Dakota Department of Environment and Natural Resources (SD DENR) Physical Habitat Characterization along with additional parameters measured for stream morphology. This assessment measured seven general physical habitat attributes important in influencing stream ecology:

· Channel Dimensions

· Channel Gradient

· Channel Substrate Size and Type

· Habitat Complexity and Cover

· Riparian Vegetation Cover and Structure

· Anthropogenic Alterations

· Channel-Riparian Interaction.

Based on the assessment data, each sampling site will be classified using Rosgen’s Geomorphologic Classification system and Schuum’s Channel Evolution model. Some of the parameters used for classification will be calculated using Geographic Information System (GIS) applications based on 1-meter resolution color digital orthoquads (DOQ). Some examples of measurements that will be estimated from DOQs are sinuosity, valley widths, and riparian extent.
