Grand River (Michigan)
The Grand River is the longest river in the U.S. state of Michigan. It runs 260 miles (420 km) through the cities of Jackson, Lansing, Grand Rapids, and Grand Haven before reaching Lake Michigan.
It drains an area of 5,572 mile² (14,431 km²). The Grand River carries an average 3,800 ft³/s (108 m³/s). It has several dams along its length but is a trout and salmon stream for much of its length.
It is estimated that 22% of the pesticide usage in the Lake Michigan watershed occurs in the Grand River drainage which accounts for only 13% of the total watershed. Much of the basin is flat and it contains many swamps and lakes; although, there is an elevation difference of 700 feet (213 m) between the source and mouth of the river.
Tributaries are the Red Cedar River, Looking Glass River, Maple River, Flat River, Thornapple River, and the Rogue River.
