Ontonagon Harbor Operation and Maintenance Activities. Lake Superior.
Abstract
The action involves operation and maintenance of Ontonagon Harbor, Michigan. Principal activities include breakwater repair, dredging, and dredge material disposal. The operation and maintenance of Ontonagon Harbor provides for safe use of the harbor by recreational craft. The use of polluted dredge material in the construction of a waste treatment facility and as fill on biologically sterile lands adjacent to the lagoons, provides advantageous use for the dredge material. The use of non-polluted dredge material as beach nourishment retards the erosion of the shoreline in the area. Adverse effects of the Corps of Engineers operation and maintenance activities in Ontonagon Harbor include increased turbidity and associated biological effects due to dredging, increased noise and congestion in the harbor, and land use alterations due to on-land placement of dredge material.
