The USGS, in cooperation with the COE, has designed and installed a system to continuously monitor changes in elevation of the river bed over the mussel bed located downstream of the Olmsted Locks and Dam project. The installed system utilizes a multi-transducer acoustic ranging system to provide river bed elevation measurements accurate to plus or minus 1 cm. The system is currently collecting data to assess the baseline sediment deposition and erosion characteristics of the mussel bed.
