2005 to 2007
USFWS retained RDG to prepare an assessment and restoration feasibility study on 7 miles of the Sycan River near Beatty, Oregon. The river has been affected by a long period of season long grazing. RDG integrated GPS data into a LiDAR/bathymetry data set characterizing the project area. A calibrated hydraulic model was developed to evaluate channel hydraulics and flood elevations associated with the flood frequency. Flood inundation maps were compared to flood air photos to determine accuracy. Recommendations included grazing cessation, revegetation, and habitat augmentation with large wood structures.
