Noteworthy Points about the Mississippi River’s Locks and Dams<\/h3>\n

The Mississippi River is an iconic American river that has been instrumental in connecting many states, communities, and individuals over its long and varied history. Along with being an invaluable transportation and trade route, it is also an important ecological and recreational resource. Though most of the river is wild and unregulated, there are still a total of 29 locks and 55 dams located along its 2,320-mile course. <\/p>\n

The locks and dams along the Mississippi River have a complicated yet important purpose. In general, they serve to manage the river’s river stages and flow regime. The locks allow large vessels to pass from one river stage to another, which is especially important for recreational boaters wanting to navigate the river. The dams help to regulate the river’s flow and reduce flooding. <\/p>\n

The Mississippi River’s 29 locks (both upper and lower) are located in various states along its course. Ten of the locks are in Minnesota, eight in Illinois, five in Wisconsin, three in Kentucky, and three in Tennessee. The locks range in size from the smallest ones on the river, which are the two dams located on the upper Mississippi, to the larger ones located near Cairo, Illinois.<\/p>\n

The 55 dams along the Mississippi supply excellent flood control benefits but also impact the river in a number of ways. The dams have caused the decline of migrating fish like sturgeon and eels, as well as blocked native fish passage, and caused the erosion of the riverbanks. They also create changes in the water temperature and turbidity, which can have an impact on the ecosystem.<\/p>\n
