What is the Mississippi River Lock System?<\/h2>\n

The Mississippi River is one of the most important waterways in the United States and is heavily utilized for commercial transportation, shipping, and recreation. The river is over 2,400 miles long and runs through or borders ten states. To help navigate and protect the river, the United States Army Corps of Engineers (USACE) operate a series of 29 locks and dams, referred to as the “Upper Mississippi River Navigation System”, to ensure safe and efficient navigation of the river. When ships pass through locks and dams, water is either let into or taken out of the locks within the system in order to lift and lower the vessels.<\/p>\n

How Does the Lock System Work?<\/h2>\n

Locks on the Upper Mississippi River Navigation System are an integral part of the river’s transportation infrastructure as they allow vessels of varying sizes to travel upstream and downstream. The locks are constructed of steel sheathed walls, steel gates and control valves, and filled by cofferdams which are long, slender tanks made of concrete, steel, or wood. They function like a staircase, raising or lowering the boats step-by-step through a system of individual locks. When the barges reach a lock, they enter a chamber, with the gates behind them closed and the chambers sealed. The amount of water inside determines the direction of the vessel, with more water in the chamber resulting in an upstream movement, while less water results in a downstream movement.<\/p>\n

How Long Does it Take to Lock Through?<\/h2>\n

The time it takes to “lock-through” (the time it takes for a vessel to enter a lock chamber and journey through it) depends on a variety of factors, such as the number of vessels present, the size of the vessel, and any traffic delays. Generally speaking, it can take anywhere from 10 minutes to several hours. Smaller barges are typically allowed to pass through quicker than larger vessels which need to snug up along the walls for stability and support. The number of vessels present in the lock complex can also affect the lock-through rate. When there are many vessels passing through, the USACE locks typically take longer as vessels must pass through sequentially or wait their turn to be allowed through.<\/p>\n

Benefits of the Lock System<\/h2>\n

The USACE locks and dams serve a variety of purposes, beyond navigation – such as providing flood control, aiding in recreation, improving the environment and assisting with navigation. The locks and dams are able to control river levels and the flow of water, making them essential to managing potential flooding on the Mississippi River. The lock system provides access to recreation areas, including fishing, swimming and boating, as well as flood control benefits. The USACE lock system helps improve the local environment, as it reduces the amount of sediment and pollutants in the water.<\/p>\n

Costs of Locking Through<\/h2>\n

Using the USACE lock system comes at a cost, both to the user and the environment. Businesses that rely on the river for transportation must pay for access to the lock system, either in the form of direct revenues or taxes. The USACE collects revenue for the use of the locks and dams, which are used to maintain the system. Additionally, passing through the lock system can have a negative environmental impact. The USACE estimates that passing through the locks and dams can lead to a decrease in water quality and an increase in pollutants, due to sediment<\/p>\n

Mississippi River Lock System Alternatives<\/h2>\n

Not all vessels on the Mississippi River use the USACE lock system. Some vessels, such as recreational boats and tow boats, have the option of using the “free river system”, which bypasses some of the lock and dam infrastructure. This option is more time-consuming, as vessels move more slowly on this section of river, but it has a lesser financial and environmental impact.<\/p>\n

Impact of Lock Closures on Shipping<\/h2>\n

There are times when the USACE locks and dams need to be closed for maintenance or other reasons. This can have a significant impact on shipping and navigation on the Mississippi River. When locks are closed, shipping is delayed, resulting in a decrease in efficiency for those who rely on the river for traffic. In some cases, the USACE will close locks for short periods of time and allow vessels to pass through in a single file, or sequentially.<\/p>\n

Effect on Local Wildlife<\/h2>\n

The USACE lock system can have both positive and negative implications for local wildlife. On one hand, the locks and dams help regulate water levels and control flooding, which can have an overall positive effect on wildlife habitats. On the other hand, the locks and dams have the potential to cause physical disruption to the river, which can disrupt the movement of certain species, such as fish. Additionally, the elevated water levels resulting from the lock system can mean that some areas experience increased levels of sedimentation, which can be damaging to certain habitats.<\/p>\n

Impact on Eco-Systems<\/h2>\n

The Mississippi River Lock System has an overall positive impact on the local environment. It helps support a balanced and diverse ecosystem, as well as aiding in the promotion of an economically stable and prosperous region. The lock system ensures that boats are able to pass through the river but does not completely disrupt the environment, as it does not interfere with the flow and pattern of the river. Additionally, the lock system helps reduce sediment and pollutants, allowing for improved water quality.<\/p>\n

Environmental Sustainability of the Lock System<\/h2>\n

The USACE has implemented various sustainability initiatives to ensure the environmental safety of the Mississippi River Lock System. A key focus of the USACE is reducing the amount of sediment and pollutants that enter the river. To this end, the USACE are using green technologies, such as electric and bio diesel powered vessels, to reduce the harm associated with navigation on the river. Additionally, the USACE is investing in green technologies to reduce the energy and water usage associated with the locks, as well as engaging in other forms of social responsibility, such as opportunities for local businesses.<\/p>\n

Economic Impact of the Lock System<\/h2>\n

The Mississippi River Lock System provides economic benefits to the region. By allowing vessels to travel up and down the Mississippi River, goods and services are able to be transported efficiently and economically. This helps to stimulate the local economy and create jobs in the areas surrounding the locks and dams. Additionally, the USACE has invested in projects to increase the efficiency and safety of the lock system, which in turn has positive economic implications.<\/p>\n

Future of the Lock System<\/h2>\n

Looking to the future, the USACE has plans to further develop the Mississippi River Lock System. With plans to expand the current infrastructure and increase access to the river, the USACE is looking to improve navigation, reduce flooding and improve both the environmental and economic impacts of the lock system. This will be achieved through both technological upgrades, such as improved control systems, as well as the continued use of green technologies to reduce the environmental impacts of the lock system.<\/p>\n

Benefits of Upgrading the Lock System<\/h2>\n
