Identification of Backwater Nursery Habitats of Colorado Pikeminnow in the Middle Green River, Utah, Using High-Resolution Remotely Sensed Imagery
- Argonne National Lab. (ANL), Argonne, IL (United States)
Low-velocity channel-margin habitats serve as important nursery habitats for the endangered Colorado pikeminnow (Ptychocheilus lucius) in the middle Green River between Jensen and Ouray, Utah. These habitats, known as backwaters, are associated with emergent sand bars, and are shaped and reformed annually by peak flows. A recent synthesis of information on backwater characteristics and the factors that influence inter-annual variability in those backwaters evaluated detailed survey information collected annually since 2003 on a relatively small sample of backwaters, as well as reach-wide evaluations of backwater surface area from aerial and satellite imagery. The material presented in this report is intended to provide documentation of the specific approach we used to collect, process, and analyze data from remotely sensed imagery of the middle Green River between the U.S. Geological Survey Jensen and Ouray gages, as well as images of the river reach, delineated backwater areas, and the calculated surface area of each.
