The Grand River is the longest river in the U.S. state of Michigan. It runs 260 miles (420 km) through the cities of Eaton Rapids, Jackson, Lansing, Grand Rapids, and Grand Haven.

[edit] Description

The Grand's headwaters begin in Somerset Township in Hillsdale County , and in Liberty Township in Jackson County, and flow through Jackson, Ingham, Eaton, Clinton, Ionia, Kent, and Ottawa counties before emptying into Lake Michigan.

Its watershed drains an area of 5,572 mile² (14,431 km²) including 18 counties and 158 townships. 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.

Tributaries are the Flat River, Looking Glass River, Maple River, Red Cedar River, Rogue River, Plaster Creek and the Thornapple River.

Every ten years the river is celebrated by an expedition along the entire length. The journey of discovery explores and documents the problems and opportunities of Michigan's Grand River and its watershed. Grand River Expedition 2010 includes a multi-disciplined team of scientists, technicians, historians, educators, students, environmental professionals, boaters and anglers, civic and business leaders, local, state and federal government representatives, writers, visual media specialists and private individuals from the general public

Grand Rapids was built on the site of a large rapids on the river, although these have disappeared after the installation of a low-head dam, and later a fish ladder.

[edit] History

Before roads, canals, and railroads, the Grand River was an important navigational route through the Lower Peninsula of Michigan, used for centuries by various Native American tribes and later by explorers and white settlers. The river was called O-wash-ta-nong, meaning "Far-away-water" because of its length.^[1]

It also formed part of a major demarcation of land ceded by Native Americans enabling U.S. settlers to legally obtain title to land in the area. In the 1821 Treaty of Chicago, the Ottawa, Ojibwe, and Potawatomi ceded to the United States all lands in Michigan Territory south of the Grand River, with the exception of several small reservations.

Grand River Avenue (or Grand River Road) was built early in the settlement of Michigan and runs from the head of navigation on the Grand to downtown Detroit. It formed an important part of an early route between Chicago and Detroit, along with the Grand itself, from Grand Rapids to Grand Haven, and Lake Michigan.
