dc.descriptionAbstract: The St. Clair River connects Lake Huron and Lake St. Clair. The river, about 40 miles long, is a vital link in the Great Lakes inland navigation system in north central United States. Low lake level experienced in Lake Huron during the early 1960's had a significant detrimental economic impact on the area. In order to increase the water level in Lake Huron, plans for using submerged sills at the head of St. Clair River were proposed. Because of the impossibility of determining by analytical means the effect of these sills on water levels in the lake and on navigation conditions in the vicinity of the sills, a fixed-bed, 1:60-scale model was used that reproduced approximately 2.8 miles of the St. Clair River and a small section of the lower end of Lake Huron. Results of the tests indicated the following. With the sill arrangements developed, water levels in Lake Huron could be raised by up to 0.75 ft without adversely affecting navigation conditions. A type of sill that would facilitate construction and reduce construction cost could be used without any significant loss in effectiveness. Shoaling along the Canadian shore can be attributed to the movement of sediment into that side of the river, the natural tendency for shoaling on the convex side of a river bend, and the effects of the eddy currents. Sills would tend to reduce the size of the eddy and the tendency for shoaling. Some deposition of sediment could occur along the left ends of some of the sills that would tend to reduce their effectiveness. However, any loss of effectiveness resulting from deposition would tend to be small.-
