2 DETROIT – The U.S. Army Corps of Engineers will begin St. Joseph Harbor emergency dredging early June, expediting the process to restore critical navigation. The Corps of Engineers identified a shoal restricting the channel depth during this year’s annual channel survey. In some areas the restriction was as little as 13 feet below low water datum, effectively closing the inner harbor to commercial navigation. “This is a true team effort,” said Detroit District Project Manager Alicia Smith. “We worked with Congressman Fred Upton’s office, Michigan Department of Natural Resources, the City of St. Joseph and local sponsors to award this contract in an expedited manner to restore critical navigation.”
