St. Clair River

The St. Clair River phase of the International Upper Great Lakes Study involved investigations into what is causing the decline in head difference (i.e., difference in water levels) between Lake Michigan-Huron and Lake Erie since 1963. The St. Clair River was dredged in the late 1950s and early 1960s, which resulted in a lowering of the water level of Lake Michigan-Huron, and a decline in the head difference between Lake Michigan-Huron and Lake Erie. Since that time, the water level of Lake Michigan-Huron has continued to decline, relative to the level of Lake Erie, causing speculation as to the cause. The declining head difference and its causes, including impacts of changes in hydraulic properties, sediment regime, hydroclimate and glacial isostatic adjustment, were studied as part of Phase 1 of the International Upper Great Lakes Study.
