The possible extension of the navigation season through the entire winter or a portion thereof has been under consideration for the Great Lakes and the St. Lawrence Seaway for a number of years. To balance the benefits and costs of such an extension it is necessary to determine the damage costs to shore structures that might result from ice loosened by ship passage. This paper is concerned with the interconnecting channels of the Lakes where there is estimated to be 18,000,000 1976 dollars worth of small, private, vulnerable shore structures. Based upon information from Corps of Engineers Permits, aerial photos and site visits, probability estimates are given for winter damage on identifiable river reaches for differing season lengths. These are related to replacement costs and tables are given showing estimated annual damage costs. Possible solutions are given which vary with ice damage susceptibility. Author
