The U.S. Geological Survey (USGS), in cooperation with the Colorado Water Conservation Board, began a study in 2011 to characterize the current hydrodynamic and sediment-transport conditions for a 2-kilometer (km) reach of the Yampa River in Deerlodge Park. Characterization of channel conditions in the Deerlodge Park reach was completed through topographic surveying, grain-size analysis of streambed sediment, and characterization of streamflow properties. This characterization provides (1) a basis for comparisons of current stream functions (channel geometry, sediment transport, and stream hydraulics) to future conditions and (2) a dataset that can be used to assess channel response to streamflow alteration scenarios indicated from computer modeling of streamflow and sediment-transport conditions. Channel response assessments can provide resource managers and planners with information to determine how streamflow alterations can be managed to maintain fluvial processes in the Yampa River while minimizing the effect on the sediment budget and fluvial geomorphology in Deerlodge Park. This report presents the results of topographic surveying of a reach of the Yampa River in Dinosaur National Monument. The report contains a description of the data collection and analytical methods used to survey the reach and to develop datasets for water management. A bathymetric map of the reach is presented with plots of hydrodynamic conditions such as stage-discharge relations, streambed grain-size information, and velocity and stream depth during the time of the survey.
