Description
The Grand River is a river in the southwestern portion of the southern peninsula of Michigan, United States, that flows into Lake Michigan on its southeastern shore. It is the longest river in Michigan, running 252 miles (406 km) from its headwaters in Hillsdale County on the southern border north to Lansing and west to its mouth on the Lake at Grand Haven. The river was famous for its mile-long, 300-yard-wide, and 10-to-15-foot-tall rapids, for which the city of Grand Rapids was named. These rapids were submerged following the construction of numerous dams, starting in 1835, and flooding of areas behind the dams. The river has not had any rapids for nearly a century.
