The Cheboygan River descends 13 feet (4.0m) in its 6-mile (9.7km) length, from 594 feet (181m) above sea level, the level of Mullett Lake, to Lake Huron at 581 feet (177m) above sea level. The river and other sections of the Inland Waterway are made accessible by locks maintained by the United States Army Corps of Engineers.
The mouth of the Black River, 3.5 miles (5.6km) south of Cheboygan, is a noted spot to look for bald eagles and other fish-eating raptors.
Cheboygan was founded as a lumbering town to cut timbers harvested from the Cheboygan River's drainage and floated down to mills (now mostly vanished) at the mouth of the river. Today, one of the biggest industries of the town and river of Cheboygan is pleasure boating up and down the river. The river is a key artery of the Inland Waterway, a pleasure-boat necklace of waterways in the northern section of Michigan's Lower Peninsula.
The river is the namesake for the city and county.[7]
