These data were compiled to determine the rate and magnitude of channel-planform change, and the topographic change of the channel and floodplain in Echo, Island, and Rainbow Parks within Dinosaur National Monument between the 1990s and 2019. The objective(s) of our study were to analyze geomorphic change within Echo, Island, and Rainbow Parks to determine the magnitude and style of channel change with respect to the past two decades of combined streamflow from Flaming Gorge Dam and the relatively unregulated Yampa River. These data represent river channel planform delineations made within a geographic information system, and topographic channel and floodplain data collected using total stations, depth sounders, Real-Time Kinematic GNSS, and multibeam sonar. These data were collected in June 2019.
