The contract, awarded May 27 to Holland-based Viking Marine Construction LLC, covers dredging at Ontonagon Harbor (Michigan) plus Port Wing and Cornucopia (Wisconsin) and carries an October 31 completion date. Hydraulic equipment will pump sediment through a pipeline to shallow-water placement northeast of Ontonagon Harbor. An Army Corps planning document estimates roughly 40,000 cubic yards of annual accumulation at Ontonagon, which was last dredged in 2024. The work is operational maintenance only and does not address navigation-structure repairs; USD 1.48 million in FY2025 funds was allocated for engineering and design on those repairs.
It details the same $1.6 million award first reported on July 28, adding the May 27 award date, the October 31 completion deadline, and the 40,000-cubic-yard annual shoaling estimate.
