Abstract : From 1961 to 1970, navigation on the St. Marys River closed for the winter from mid-December to mid-April. Subsequent extension of the navigation season to include the winter months resulted in complaints of shoreline and dock damage along the navigation channels. Studies were initiated to examine the potential for navigation-caused damage, but information on damage during a navigation-free winter was lacking. Since limited navigation was planned during the 1979-80 winter, the St. Marys River System could be examined under relatively undisturbed conditions. The report examines potential navigation-related damage mechanisms and presents data from the closed navigation season. The results are compared with information collected during previous periods with winter navigation. (Author)
