Videomonitoring Performance of the St. Marys River Ice Islands and Ice Boom

In 1997, six islands were constructed to stabilize the ice cover at the entrance to the Little Rapids Cut on the St. Marys River at Sault Ste. Marie, Michigan. It was hoped that the artificial islands would eliminate the need for an ice retention boom installed annually since 1974 by the Corps of En...

Description
Summary:In 1997, six islands were constructed to stabilize the ice cover at the entrance to the Little Rapids Cut on the St. Marys River at Sault Ste. Marie, Michigan. It was hoped that the artificial islands would eliminate the need for an ice retention boom installed annually since 1974 by the Corps of Engineers. The U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) videomonitored the performance of the ice control islands during the winters of 2000 and 2001. Conclusions were that, although the islands helped stabilize the ice cover and protected the ice boom from impacts from large ice floes, the boom should still be installed as it significantly speeds ice cover formation at the Little Rapids Cut entrance.
