where does the grand river start and end in michigan
Grand River (Michigan) As the glacial ice receded from what is the central Lower Peninsula of Michigan around 11,000 years ago, the Maple River and lower Grand River served as a drainage channel for the meltwater. The channel ran east to west, emptying into proglacial Lake Chicago, the ancestor of Lake Michigan. Today the Grand River rises in Somerset Township in Hillsdale County and Liberty Township in Jackson County, and flows through Jackson, Ingham, Eaton, Clinton, Ionia, Kent, and Ottawa counties before emptying into Lake Michigan. Its watershed drains an area of 5,572 square miles (14,430 km2), including 18 counties and 158 townships. Tributaries of the river include (beginning near river source and travelling downstream): Portage River, Red Cedar River, Looking Glass River, Maple River, Bellamy Creek, Flat River, Thornapple River, Rogue River, Coldbrook Creek, Plaster Creek, Bass River, and Crockery Creek. 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 lake's total watershed. Much of the basin is flat, and it contains many swamps and lakes.
Mississippi River The Mississippi River is the chief river of the second-largest drainage system on the North American continent, second only to the Hudson Bay drainage system.[13][14] The stream is entirely within the United States (although its drainage basin reaches into Canada), its source is Lake Itasca in northern Minnesota and it flows generally south for 2,320 miles (3,730Â km)[14] to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 31 U.S. states and two Canadian provinces between the Rocky and Appalachian Mountains. The Mississippi ranks as the fourth-longest and fifteenth-largest river in the world by discharge. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.[15][16]
