\nHistory and Development of Locks on the Mississippi River
\n<\/h2>\n

The development of locks on the Mississippi River is an essential factor in today’s transportation of goods throughout the United States. The first structures were built in the 1850s, with the first completed lock and dam system in Jefferson City, Missouri. From then on, the idea of engineering larger and more efficient locks was put into motion, transforming the great river into one of the most important trade and transportation hubs of the nation. With the addition of the historic Sault Sainte Marie locks in 1690, technology had been introduced that allowed smaller boats to go further inland and facilitate commercial activity. This system was improved and expanded by the U.S. government throughout the 19th century in order to connect port cities such as New Orleans and St. Louis.<\/p>\n

During the development of the locks, engineers, politicians and scientists discussed the ideal construction and design of these structures, as well as the risks in using them. In 1885, for instance, the engineer Evans argued about the importance of “permanent and substantial” designs that would not diminish the power of the river. Meanwhile, scientist de Waal Malefyt advanced the idea of allocating enough water to the locks, in order to maintain the river’s velocity. Discussions such as this helped to create more stable designs, which in turn gave rise to the great lock and dam systems of today.<\/p>\n

Current Lock System on the Mississippi River

Today, the Mississippi is home to a significant number of locks and dams. These systems prevent flooding, protect villages and towns from the river’s changing water levels and rules, and also make commercial navigational activities easier. According to the U.S. Army Corps of Engineers, the locks and dams regulate water levels along the entire course of the Mississippi, from St. Louis to New Orleans. This allows for navigation of goods from one port city to the other, as the dams prevent the river from rising too high or falling too low in certain areas.<\/p>\n

The usage of the locks is constantly supervised by the Corps of Engineers, as there are several hazards that they must take into account. For instance, sometimes the hydroelectric dams do not provide enough electricity to the locks, which in turn can cause disruption in the operation and potential danger to vessels. In addition, the locks require constant maintenance and repairs due to the environmental damage and wear-and-tear over time.<\/p>\n
