Surveyed coordinates and elevations in a 2020 resurvey of previously established cross sections on the Green River between Jensen and Ouray, Utah These data were compiled for/to National Park Service and Upper Colorado River Endangered Fish Recovery Program. Objective(s) of our study were to resurvey previously established cross sections on the Green River, Utah, in, and upstream, from Ouray National Wildlife Refuge to document changes in channel width, depth, and cross-sectional area. These data represent the 2020 resurvey coordinates and elevations of previously established cross sections (1994 - 1996) on the Green River. These data were collected in the Green River between Jensen and Ouray, Utah from October 11-16, 2020. These data were collected by Ronald Griffiths and Joel Unema from the U.S. Geological Survey using real-time kinematic (RTK) GPS positioning....

Objective(s) of our study were to resurvey previously established cross sections on the Yampa and Little Snake rivers in the Deerlodge Park area to document changes in channel width, depth, and cross-sectional area. A secondary purpose of this study was to document the location of the cross-section endpoints using modern Global Positioning System (GPS) measurements so that future researchers may easily replicate these surveys. These data represent the 2017 resurvey coordinates and elevations of previously established cross sections on the Little Snake and Yampa rivers. These data were collected in Lily...
