Tennessee Rivers & Water Quiz
Explore the geography of Tennessee’s significant rivers, dams, and watersheds with these 10 questions.
Tennessee Rivers & Water Quiz: Quick Study Notes
Tennessee is rich in water resources, primarily dominated by the mighty Tennessee River and its extensive network of tributaries. The geography of the state’s water bodies is heavily influenced by the Tennessee Valley Authority (TVA) and its series of dams, which have profoundly shaped flood control, navigation, and hydroelectric power generation throughout the region. Understanding the major rivers, these crucial dams, and the concept of watersheds is key to appreciating Tennessee’s environmental and economic landscape.
Formed near Knoxville by the confluence of the Holston and French Broad Rivers, it’s the largest tributary of the Ohio River by discharge.
The Tennessee Valley Authority (TVA) manages a system of 29 dams on the Tennessee River and its tributaries, primarily for flood control, navigation, and power generation.
A watershed is an area of land that drains all the streams and rainfall to a common outlet, such as a river, lake, or ocean. Tennessee contains parts of several major watersheds.
Important tributaries include the Clinch, Duck, Elk, Hiwassee, and Little Tennessee Rivers, all contributing significantly to the mainstem’s flow.
Key Takeaways
- The Tennessee River is the central waterway of the state, crucial for its geography and economy.
- The Tennessee Valley Authority (TVA) operates a vast system of dams primarily for flood control, improved navigation, and generating hydroelectric power.
- Tributary rivers like the Holston, French Broad, and Clinch are essential for contributing water volume to the Tennessee River.
- A watershed defines the land area that channels water into a specific river or body of water.
- Dams have created numerous large reservoirs (lakes) in Tennessee, fundamentally altering natural river ecosystems and enabling new forms of recreation and development.
- Understanding these water systems is vital for appreciating Tennessee’s rich natural resources and human impact.
Frequently Asked Questions
What is the Tennessee River?
The Tennessee River is a major tributary of the Ohio River, approximately 652 miles (1,049 km) long, flowing through the southeastern United States. It’s formed by the confluence of the Holston and French Broad Rivers and is a central feature of the Tennessee Valley.
What is the main purpose of TVA dams?
The primary purposes of TVA dams are flood control, improving navigation, and generating hydroelectric power. They also support recreation, water supply, and water quality management.
What is a watershed?
A watershed, also known as a drainage basin, is an area of land where all of the water that falls within it or drains off of it goes into a common outlet, such as a river, lake, or ocean.
Which rivers form the Tennessee River?
The Tennessee River is formed in Knoxville, Tennessee, by the convergence of the Holston River and the French Broad River.
What is the largest lake formed by a TVA dam in Tennessee?
Kentucky Lake, formed by Kentucky Dam on the Tennessee River, is the largest lake by surface area that lies significantly within Tennessee, although the dam itself is in Kentucky.
