Dredging and Channel Maintenance Damages will focus on those costs associated with additional dredging required as a result of significantly lower water levels, or associated with excessive sedimentation of channels in high water periods or during altered current conditions. In addition any maintenance required to federal harbor structures as a result of either high or low lake levels will be examined.

This task was performed as a Value Engineering Study, led by the the USACE Detroit District, with participation from Baird & Associates and WES. USACE representatives from the Grand Haven, Michigan and Kewaunee, Wisconsin also participated.

The full report may be downloaded from the LMPDS Document Clearinghouse. This report summarizes the potential economic impacts of three of the water level scenarios on federal projects in the prototype counties and it is currently being evaluated as to its applicability to other federal structures in Lake Michigan.
