Bowen, Z. H., Bovee, K. D., Waddle, T. J. Effects of Channel Modification on Fish Habitat in the Upper Yellowstone River, Final Report to the USACE (U. S. Army Corps of Engineers), Omaha (OFR-03-476). 2003. 50 pp., 8.5" x 11". Description: This study examined the effects of bank armoring and flow training structures on the availability of SSCV (shallow depth, slow current velocity) habitat. The authors mapped representative study reaches in the upper Yellowstone River and used hydrodynamic models and hydrograph data to describe the availability of SSCV habitat during different hydroperiods. The authors focused on availability of SSCV habitat because of its function as a refugium and nursery habitat for young fish.
