From the depths of Watauga Lake to the sunken trees of Reelfoot Lake, Tennessee is home to dozens of beautiful, unique lakes. While they all have something special to offer, only one boasts the title of having the “clearest water” in the state.
Norris Lake, located just north of Knoxville, is one of the most popular lakes in Tennessee. It offers a wide variety of recreation opportunities and is known for its striking green hue and crystal waters.
Nestled in the Appalachian Mountains, Norris Lake spans five counties and offers more than 800 miles of shoreline, 22 marinas, and more than 50 islands. Also known as Norris Reservoir, this sprawling man-made lake is known for family-friendly activities like fishing, swimming, boating, waterskiing, hiking, and of course, its calm, crystal waters. The nearby Norris Dam State Park also has numerous designated areas for picnicking and camping, making it an ideal travel destination for lake lovers of all ages.
Why Is Norris Lake’s Water So Clear?
The striking green water of Norris Lake is so clear that in 2024, USA Today named it one of the 10 best lakes for swimming in the country—besting both Lake Superior and Lake Michigan!
Norris Lake is widely considered one of the cleanest lakes managed by the Tennessee Valley Authority (TVA). While a number of things contribute to the color and clarity of lake waters, experts believe that the area’s limestone-rich terrain is to thank. The high limestone content in the rocks surrounding Lake Norris helps filter sediment and algae and contributes to the water’s green hue.
Lake Norris’ considerable depth (it reaches 210 feet in some parts!) also adds to the clarity of the water. The reservoir further benefits from its creator, the Norris Dam. The 92-year-old dam filters out trash, contaminants, and other things from the Clinch River that could sully the lake’s pristine appearance.
Where To See Norris Lake’s Waters
Norris Lake winds across 33,840 acres of beautiful East Tennessee real estate. With 809 miles of shoreline, the lake provides endless opportunities for swimming, fishing, hiking, boating, camping, and other outdoor activities. The 3.1-mile River Bluff Trail is a perfect option for wildflower lovers, and mountain bikers will love the Loyston Point trail system. Rent a boat for the day from one of the lake’s many marinas and resorts—just don’t forget a fishing pole.
After working up an appetite, you can check out one of many marina restaurants and bars. The Harbor Grill at Stardust Marina offers lake-side dining, live music, and Friday night crawfish boils during the summer. Be sure to stop at nearby Clinch River Brewing for New Orleans-inspired food and local beer.
