When combined with the Missouri river, it makes up the fourth longest river system in the world after the Nile, Amazon and Yangtze Rivers. As a result, the U.S. Congress authorized a project called the Old River Control Structure, which has prevented the Mississippi River from leaving its current channel that drains into the Gulf via New Orleans.[60]. [89][90], Geologists believe that the lower Mississippi could take a new course to the Gulf. The river is about 2,320 miles (3,734 km) long and its drainage basin covers an area of 1,151,000 square miles (2,981,076 sq km). Where does Mississippi start?

The Mississippi River flows south from Northern Minnesota at Lake Itasca to Louisiana into the Gulf of Mexico. Where does the Aegean Sea start? On the lower Mississippi, from Baton Rouge to the mouth of the Mississippi, the navigation depth is 45 feet (14 m), allowing container ships and cruise ships to dock at the Port of New Orleans and bulk cargo ships shorter than 150-foot (46 m) air draft that fit under the Huey P. Long Bridge to traverse the Mississippi to Baton Rouge. What county is Grand Island NY in, Where is Somers New York? Until the 1950s, there was no dam below Lock and Dam 26 at Alton, Illinois.

The area of the Mississippi River basin was first settled by hunting and gathering Native American peoples and is considered one of the few independent centers of plant domestication in human history. Where Does the Mississippi River Start and End? In 1878, Congress authorized the Corps to establish a 4.5-foot-deep (1.4 m) channel to be obtained by building wing dams that direct the river to a narrow channel causing it to cut a deeper channel, by closing secondary channels and by dredging.

Another possible course change for the Mississippi River is a diversion into Lake Pontchartrain near New Orleans. If this facility were to fail during a major flood, there is a strong concern the water would scour and erode the river bottom enough to capture the Mississippi's main channel. Baton Rouge: Louisiana State University Press, 2007. The Hennepin Canal roughly follows the ancient channel of the Mississippi downstream from Rock Island to Hennepin, Illinois. Aside from its association with the Mississippi, Lake Itasca is very significant in a variety of other ways. The Corps now actively creates and maintains spillways and floodways to divert periodic water surges into backwater channels and lakes, as well as route part of the Mississippi's flow into the Atchafalaya Basin and from there to the Gulf of Mexico, bypassing Baton Rouge and New Orleans. Lake Pepin, a natural lake formed behind the delta of the Chippewa River of Wisconsin as it enters the Upper Mississippi, is more than 2 miles (3.2 km) wide. The sport of water skiing was invented on the river in a wide region between Minnesota and Wisconsin known as Lake Pepin. Lock and Dam No. The Mississippi River starts at Lake Itasca in north central Minnesota and travels 2,350 miles to its endpoint at the Gulf of Mexico. The Middle Mississippi is relatively free-flowing. 1 was completed in Minneapolis, Minnesota in 1917. [citation needed] During the 2011 floods, the Corps of Engineers opened the Morganza Spillway to 1/4 of its capacity to allow 150,000 cubic feet per second (4,200 m3/s) of water to flood the Morganza and Atchafalaya floodways and continue directly to the Gulf of Mexico, bypassing Baton Rouge and New Orleans. Above the dam, the river's elevation is 799 feet (244 m). Sea Distance Calculator. The southernmost extent of this enormous glaciation extended well into the present-day United States and Mississippi basin. What county is East Fishkill NY in, Where is Orchard Park New York? There is a debate about the true length of this river and different organizations give different lengths. Since the 20th century, the Mississippi River has also experienced major pollution and environmental problems – most notably elevated nutrient and chemical levels from agricultural runoff, the primary contributor to the Gulf of Mexico dead zone.
