Black River, MI (PH)

The Black River has its source in the northern part of Sanilac County, MI, is about 60 miles long, and flows in a southeasterly direction into the St. Clair River at Port Huron, MI. The project was authorized by Rivers and Harbors Acts of September 19, 1890; July 13, 1892; September 22, 1922; July 3, 1930; August 30, 1935; and, April 23, 1970. The existing project provides for a channel 20 feet deep from deep water in the St. Clair River to the Grand Trunk Western Railroad Bridge, 160 feet wide at the mouth, decreasing to 100 feet, about 800 feet from the mouth; thence 100 feet wide for 2,600 feet, decreasing to 75 feet for a distance of 4,800 feet; widening two bends to 100 feet, one at the foot of 12th street, and the other below the Grand Trunk Western Railroad Bridge; for a settling basin 75 feet wide and 20 feet deep, beginning at the Grand Trunk Western Railroad Bridge in Port Huron and extending upstream a distance of about 2,300 feet; and then for a distance of 2.6 miles a 100-foot wide river channel, 8 feet deep to the I-94 Bridge where it decreases to 6 feet deep and continues to the vicinity of the Black River Drainage Canal, with suitable widening where required at bends in the channel. There are docks on both sides of the Black River near its mouth, and between these docks and the upper limit of improvement there are several docks varying in length from 100 to 500 feet. All docks are privately owned. Public recreational boating facilities constructed by state and local agencies are available, as are privately owned and operated marinas.
