Book excerpt: An ice boom at the head of LIttle Rapids Cut was first installed as part of the Great Lakes and St. Lawrence Seaway Navigation Season Extension Demonstration Program. to help stabilize the ice cover in Sault Harbor and thus moderate ice problems in Little Rapids Cut and act as an aid to winter navigation. Upon conclusion of the Demonstration Program, a decision was made to reinstall the ice boom each winter for an indefinite period. Authority for installation of the ice boom was given to the Sault Area Office as part of its regular operations. This report documents the operation of the Little Rapids Cut boom during the 1983 - 1984 winter season. The boom system stabilized the ice cover in Sault Harbor, reducing the extent of ice accumulation in Little Rapids Cut and reducing the amount of ice in the Sugar Island ferry crossing. Thus, the liklihood of emergency cutbacks in the outflow from Lake Superior that would cause power losses at the hydropower plants has lessened. Also, the boom has contributed to more reliable winter transportation between Sugar Island and the mainland. Keywords: Ice boom; Water levels; Flows and ice thickness; Soo Harbor; Little Rapids Cut.

This book was released on 1984 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ice problems developed in the Sault Ste. Marie, Michigan, portion of the St. Marys River because of winter navigation Passing ships and natural influences moved ice from Soo Harbor into Little Rapids Cut in sufficient quantities to jam, cause high water in the harbor, and prevent further ship passage. After physical model and engineering studies, two ice booms with a total span of 1375 ft (419 m) with a 250-ft (76-m) navigation opening between were installed at the head of Little Rapids Cut in 1975. A modest field study program on the booms was conducted for the ensuring four winters to determine ice and boom interaction and the effects of ship passages on the system. Forces on some anchors were recorded and supplemental data were taken by local personnel. Several reports have been written about the booms' early operations. This paper presents four-year summary of the main effects of the booms on ice and ship interaction and vice versa. Throughout the four winter seasons, the small quantities of ice lost over and between the booms were manageable. Ships usually passed through the boom without influencing the boom force levels, but at time they brought about large changes. One boom needed strengthening, and artificial islands were added for upstream ice stability. Coast Guard icebreakers were also a necessary part of winter navigation in this area.
