St. Clair River has changed, accounting for 7-14 cm of total head decline

There have been changes in the morphology and hydraulic properties of the St. Clair River, and this has resulted in an increase in the conveyance of the St. Clair River, sometime since the last navigational dredging project in 1962, based on the findings of multiple hydraulic modelling and data and flow analyses. The changes observed were not confined to a particular section of the river. Analysis and modelling using data collected at water level stations along the St. Clair River indicated that there were changes in conveyance in many, but not all, reaches of the river. In some of these reaches, conveyance increased over time, while in others conveyance decreased. Localized features of the channel, such as deep sections, have little effect on conveyance in the river. The flow in the St. Clair River is not controlled by any one section, but rather by the conveyance in the entire channel and the difference in levels between Lake Michigan-Huron and Lake St. Clair.
