Has St. Clair morphology changed since 1962, what initiated it, and when?

An understanding of the sediment regime of the St. Clair River is a vital first step in addressing the Study’s central question of what factors are responsible for the lake-to-lake fall between Lake Michigan-Huron and Lake Erie. Therefore, a key aspect of the study was to document and understand the sediment regime of the St. Clair River, in particular with respect to three key science questions: 1) Has the St. Clair River morphology been altered since the 1962 dredging? 2) Is the St. Clair River bed stable or eroding? 3) If it is eroding, what initiated it, and when? The work involved projects examining the geomorphic history of the river, the type of material on and beneath the river bed, the river bed topography and morphology, changes to river bed topography since the 1962 deepening of the navigation channel, and the present-day patterns and rates of bed erosion, deposition and sediment transport along the river in relation to the known hydraulic conditions in the river.
