South Haven Maintenance Dredging Project

Award-winning use of surveying and mapping technology

Record low water levels in the Black River and Lake Michigan necessitated maintenance dredging efforts to keep the waterways navigable for the local boating industry.

Obtaining accurate bathymetric data was essential to the efficiency and timeliness of the project.  Even while surface water elevations were in constant flux due to weather conditions and hydrostatic forces associated with riparian waters and Lake Michigan, the GPS based bathymetric survey system was able to produce quality control checks of less than one tenth of one foot throughout project sites.
