Norris Hydroelectric Dam – Rocky Top, Tennessee

Norris Hydroelectric Dam - Rocky Top, Tennessee

Norris Dam, completed in 1936, was the first major project of the Tennessee Valley Authority (TVA), a New Deal initiative aimed at modernizing the Tennessee Valley region. Constructed on the Clinch River in eastern Tennessee, the dam was designed for flood control, hydroelectric power generation, and economic development. Named after Senator George W. Norris, a strong advocate for public power, the dam was a centerpiece of President Franklin D. Roosevelt’s vision for rural electrification and economic recovery. Built during the Great Depression, the project provided thousands of jobs and stimulated local economies. The dam’s completion marked the beginning of TVA’s extensive efforts to transform the Tennessee River system, eventually leading to the creation of a network of dams, reservoirs, and power plants across the region.

The Tennessee Valley Authority (TVA) was established in 1933 to address severe flooding, deforestation, and economic hardship in the Tennessee Valley, one of the most impoverished regions in the U.S. By constructing dams like Norris, TVA provided cheap hydroelectric power, improved navigation, and helped control soil erosion. However, the project also had significant social costs—more than 2,900 families were displaced to create the Norris Reservoir, leading to widespread resentment among some residents. Despite this, TVA’s initiatives modernized agriculture, brought electricity to rural areas, and encouraged industrial growth, transforming the region into an economic powerhouse. Today, Norris Dam remains a vital part of TVA’s infrastructure, supporting power generation, recreation, and environmental conservation efforts.

Ohio River Road Damage – Clarksville, Indiana

Ohio River Road Damage - Clarksville, Indiana

The image depicts damage to road running parallel to the Ohio River, in Clarksville , Indiana after recent high water and flooding led to bank erosion. Louisville, Kentucky lies on the opposite side of the Ohio River.

The Ohio River experiences frequent flooding and bank erosion, primarily due to heavy rainfall, snowmelt, and its extensive tributary system. Major floods have historically impacted cities along the river, with some of the worst occurring in 1937, 1997, and 2018. The Great Flood of 1937 was the most devastating, submerging entire towns, displacing hundreds of thousands, and causing widespread destruction from Pittsburgh to Cairo, Illinois. Modern flood control measures, including reservoirs, levees, and the lock-and-dam system managed by the U.S. Army Corps of Engineers, help mitigate extreme flooding. However, heavy storms and prolonged wet seasons still cause periodic water level surges, leading to localized flooding and property damage.

Bank erosion along the Ohio River is another persistent issue, caused by fast-moving currents, seasonal floods, and human activities like dredging and construction. Erosion leads to the loss of farmland, damage to infrastructure, and increased sedimentation in the river, which can affect water quality and aquatic habitats. In urban areas, failing riverbanks threaten roads, bridges, and homes, requiring costly stabilization efforts. Some communities use riprap (rock barriers), retaining walls, and vegetation planting to slow erosion, but long-term riverbank stability remains a challenge. As climate patterns shift, increased rainfall intensity may worsen both flooding and erosion, prompting further investment in floodplain management and conservation efforts.

The Ohio River Lock and Dam System is a critical infrastructure network designed to regulate water levels and facilitate navigation along the 981-mile-long Ohio River. Managed primarily by the U.S. Army Corps of Engineers, the system consists of a series of locks and dams that maintain a consistent channel depth, allowing for the safe and efficient passage of commercial barges, recreational boats, and other vessels. Prior to modern improvements, the river was unpredictable, with natural shallows and seasonal variations making navigation difficult. The system, initially developed in the early 20th century, replaced outdated wooden wicket dams with more advanced high-lift structures that provide year-round navigability. Today, the system supports billions of dollars in commerce, primarily transporting coal, petroleum, steel, and agricultural products.

The lock and dam system works by creating a series of controlled pools along the river, allowing vessels to “lock through” from one water level to another. Each lock chamber is a large, enclosed space with gates at either end that open and close to let water in or out, raising or lowering boats as needed. Notable installations include the Markland Locks and Dam, McAlpine Locks and Dam, and Olmsted Locks and Dam, the latter being the most advanced and expensive project in the system. In addition to navigation, the system plays a key role in flood control, water supply, and hydroelectric power generation, benefiting communities along the river. Continuous modernization efforts ensure the system remains efficient, as aging infrastructure and increasing traffic demand ongoing improvements.
