The Mississippi River is one of the busiest and largest rivers in the US. Spanning roughly 3600 miles from Minnesota to New Orleans, Louisiana, the river has long been a major trade and transportation route for goods, people and commodities. Generating just over $400 billion in 2003 for agriculture and supporting millions of jobs, the Mississippi River has also had several thousand locks and dams constructed on it by the U.S. Army Corps of Engineers for flood control, navigation, and power generation. The main purpose of these locks and dams is to raise and lower the water levels of the river, meaning boats can be directed from one water level to another.<\/p>\n

The Mississippi Lock and Dam System works by using hydraulic lift mechanisms to create a series of locks and dams along the Mississippi River. This system helps to regulate the depth of the river, allowing ships and other commercial vessels to travel on it. There are currently 18 active locks and dams along the Mississippi River which have been in place since the 1930s. These primarily consist of Lock and Dam Number 1 near Lake Itasca in Minnesota and Lock and Dam Number 18 near Cairo, Illinois. These locks and dams are created to regulate the depth of the river and also help to control flood levels. The river also has smaller locks and dams constructed over areas that have less navigable waters.<\/p>\n

Lock and Dam Number 1 is the oldest of the Mississippi River locks and dams and was built in the 1930s. It is the most frequently used of the locks and dams system and is used to regulate the water level in the river and control floodwaters. The lock and dam is operated by the U.S. Army Corps of Engineers and is located in Lake Itasca, Minnesota, where the Mississippi River begins. The other seventeen locks and dams in the system are winding down the Mississippi River and provide regulated depths for boat and barge operations for the various types of goods transported on the river.<\/p>\n

The U.S. Army Corps of Engineers has been managing the Lock and Dam System on the Mississippi River since the 1930s. This is done by monitoring the water level of the river and maintaining the locks and dams in order to control the depth of the river and the movement of boats and barges. The Corps’ efforts have been a significant factor in the river’s growth and development. The locks and dams also help to control flooding along the Mississippi River, helping to protect communities and businesses in the area.<\/p>\n
