Erosion, Dredging and the Great Lakes
The International Joint Commission will study whether erosion from dredging on the St. Clair River is causing water levels to drop in Lakes Huron and Michigan. It will submit a series of updates on its progress and draft a report by February 2009.
The study comes after the Georgian Bay Association claimed that erosion on the northern end of St. Clair from dredging is causing a loss of 2.5 billion gallons of water daily from Lakes Huron and Michigan.
Water levels on the two lakes have fallen since the late 1990s. Drought and evaporation are also reasons for the drop, but erosion plays a role and could be fixed some believe. Seven U.S. senators from the Midwest sent the International Joint Commission a letter asking for the study.
