Lock and Dam Russellville, AR: A Comprehensive Guide
The Lock and Dam at Russellville, Arkansas, is a marvel of modern engineering and a testament to the importance of water management in the United States. Located on the Arkansas River, this facility plays a crucial role in the navigation, flood control, and hydroelectric power generation. Let’s delve into the various aspects of this impressive structure.
History and Construction
The construction of the Lock and Dam at Russellville began in 1976 and was completed in 1980. The project was part of the larger Arkansas River Navigation System, which aimed to improve navigation and flood control along the river. The dam is one of the largest in the United States, with a height of 234 feet and a length of 2,620 feet.
Navigation and Flood Control
The primary purpose of the Lock and Dam at Russellville is to facilitate navigation on the Arkansas River. The lock allows boats to pass through the dam, enabling them to travel between the upper and lower sections of the river. This is particularly important for commercial traffic, as it provides access to the heartland of the United States.
In addition to navigation, the dam plays a crucial role in flood control. By regulating the flow of water, the dam helps to prevent flooding in the surrounding areas. This is especially important during the spring, when heavy rains can lead to significant flooding along the Arkansas River.
Hydroelectric Power Generation
The Lock and Dam at Russellville also generates hydroelectric power, contributing to the nation’s energy supply. The facility has two generating units, which can produce a total of 60 megawatts of electricity. This power is used to supply local communities and businesses, as well as to feed into the regional power grid.
Design and Engineering
The design of the Lock and Dam at Russellville is a testament to the ingenuity of engineers. The structure features a concrete gravity dam, which is supported by its own weight. This design allows the dam to withstand the immense pressure exerted by the water behind it.
The lock itself is a double-chambered structure, measuring 110 feet wide and 600 feet long. This design allows for the passage of large vessels, including barges and towboats. The lock operates using a series of gates and mechanical systems, ensuring smooth and efficient navigation.
Environmental Impact
The Lock and Dam at Russellville has had a significant impact on the local environment. While the dam provides numerous benefits, it has also raised concerns about the impact on aquatic life and the natural flow of the river. To mitigate these concerns, the U.S. Army Corps of Engineers has implemented various measures, including fish ladders and water quality monitoring programs.
Community and Economic Impact
The Lock and Dam at Russellville has had a profound impact on the local community and economy. The improved navigation and flood control have made the area more attractive for businesses and residents. The dam also provides employment opportunities for local workers, including engineers, maintenance personnel, and security staff.
In addition, the dam has become a popular tourist destination. Visitors can take a guided tour of the facility, learn about its history and operation, and even witness the lock in action. This has helped to boost the local economy and create new job opportunities in the tourism sector.
Conclusion
The Lock and Dam at Russellville, Arkansas, is a remarkable engineering achievement that serves multiple purposes. From navigation and flood control to hydroelectric power generation, this facility plays a vital role in the region’s development and well-being. While it has raised some environmental concerns, the U.S. Army Corps of Engineers has taken steps to mitigate these issues. Overall, the Lock and Dam at Russellville stands as a testament to the importance of water management and the ingenuity of engineers.
