The White River Watershed Partnership (WRWP) is leading an effort to characterize road-stream crossings (RSXs) in the Upper White River (western Michigan) both before and after remediation. The major goals of this work are threefold: 1) to identify and prioritize RSXs most in need of remediation due to their impact on stream connectivity, hydrology and erosion; 2) to facilitate remediation by enhancing public awareness and assisting in fund raising; and 3) to conduct pre- and post-remediation surveys and modeling that document the benefits of RSX improvements for the benthic macroinvertebrate community, hydrological characteristics, and reduction of erosion/sedimentation. The methods employed in this effort include: 1) RSX assessments using protocols standard to the Great Lakes basin; 2) physical surveys of stream profiles, flow characteristics, and substrate texture; 3) Stream Quality Indices based on indicator organisms; and 4) both modeling and measurements of erosion and in-stream sediment transport.
