This book was released on 1975 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proposed project is to perform maintenance dredging of the Saginaw River and Saginaw Bay Federal Navigation channels. Dredging will be performed by a Government-owned hopper dredge. Approximately 140,000 cubic yards of polluted material dredged from the river, from the Detroit and Mackinac Railroad Bridge to the upper limits of the harbor, is placed on the confined disposal area on Middle Ground Island. The polluted channel section from the D & M R.R. bridge to the river mouth and the section throughout the inner bay will not be dredged until a confined disposal site is constructed to contain this dredged material. The average annual volume of shoaling throughout the project is approximately 840,000 cubic yards. (Author).

Book excerpt: The proposed action is to perform maintenance dredging of the St. Clair River when required to remove shoaling. Average annual volume removed is approximately 130,000 cubic yards consisting primarily of gravel, sand, and silt. The material removed will be disposed of deep water or placed on selected onshore sites. All materials scheduled for removal from the St. Clair River have been classified by the U.S. Environmental Protection Agency as suitable for unrestricted open water disposal. Most maintenance operations are accomplished by hopper dredge, but a derrickboat utilizing a bucket dredge removes channel obstructions if rock rather than sand or silt must be removed. The open water disposal sites used by the hopper dredge are located in the deep water of Lake Huron several miles north of the Blue Water Bridge and during 1976 in deep water of the North Channel adjacent to Point Au Chenes. The use of the North Channel disposal area will be discontinued after the 1976 work season. In subsequent years sediments removed from the lower reaches of the river will be stockpiled at an onshore site furnished by the Michigan Department of Natural Resources for future project was uses in maintenance and further development of the St. Clair Flats Wildlife Area.

Book excerpt: Resumption of the removal of polluted material will temporarily degrade the water quality and localized turbid problems are anticipated to be encountered at areas during removal of the rocky material. Disposal of the dredged material into their respective disposal sites may affect the aquatic ecosystem. Continued economic and social stability of the Great Lakes is dependent upon commercial navigation which requires maintenance dredging of the connecting channels of the Detroit River. Short-term increased turbidity and temporary water quality degradation in the area of operation are effects of maintenance dredging. Aquatic life in the dredging areas will be disturbed or destroyed. Disposal of the dredged sediments will alter existing habitats and may otherwise adversely affect organisms at the disposal areas. Dredging alternatives include: (1) alternative dredge types; (2) discontinue maintenance dredging completely; (3) dredge the connecting channels to a lesser depth; and (4) wastewater management. Implementation of the alternatives will cause economic or social impacts on the Detroit River area as well as the Great Lakes region. Alternatives to the disposal methods are examined. In terms of economic and engineering feasibility, irretrievable resources and minimal ecological disruption, the process of confined disposal of polluted materials and open water disposal for non-polluted sediments offers the best alternatives at present.
