government assistance dredging a small channel

This channel flows between Squirrel and Walpole Islands into Lake St. Just downstream of Russell Island a small channel, the Chematogan Channel, splits off from the South Channel. The South Channel is the main navigation channel through the St. Downstream of Dickinson Island these two channels divide into smaller ones, all flowing into Lake St. Upstream of Dickinson Island the Middle Channel splits away from the North Channel. The North Channel flows between Harsens Island and the Michigan mainland. Three miles below Roberts Landing, at Algonac, Michigan, the river divides into two channels around Russell Island, the North and South Channels. This small channel, which carries about five percent of the total river flow, meanders through marsh and wetland, splitting into several smaller channels that empty into Lake St. The channel first splits about 1-1/2 miles below Roberts Landing, as the Chenal Ecarté leaves the main channel and flows to the east. In this reach the river divides into several meandering channels as it flows across a delta area, known as the St. Clair River extends about 9 miles to Lake St. Located in this reach are Stag and Fawn Islands and a middle ground shoal opposite the City of St. The middle reach, which extends downstream for approximately the next 27 miles, is about one-half mile wide and has channel depths varying from 27 to 50 feet.

Clair River occur in this reach near the Blue Water Bridge. The upper reach, extending downstream from Lake Huron to a point about three miles below the International Blue Water Bridge, is about 800 feet wide at its narrowest point and has mid-channel depths varying from about 30 to 70 feet. The fall in water level from Lake Huron to Lake St. Clair River has three distinct reaches having a length of about 39 miles, including the St.
