Metro Parks begins work to improve Lake Watauga’s water quality


Work scheduled to begin next week

WHAT: The improvement of Lake Watauga’s water quality is part of the Centennial Park Master Plan, which was completed in 2011.  The plan calls for an integrated strategy that will ensure a cleaner, clearer, more beautiful lake. The process to improve Lake Watauga’s water quality includes: dredging of lake sediment, the refilling of the lake, the installation of a new aeration and circulation system and the placement of floating wetland islands.

Additional improvements to the water quality, which are scheduled for later in the year, include: an increase in the amount of Cockrill Spring water flowing to Lake Watauga, rain gardens to filter stormwater runoff before it enters the lake, and recharge beds that will increase the amount of stormwater that is returned to the water table instead of entering the storm sewer system. 

WHEN: Mid - February 

TIMEFRAME: Completion Spring 2014.  

WHERE: Lake Watauga, Centennial Park, 2500 West End Avenue, Nashville TN 

WHY: Decades of sediment accumulation, poor water circulation and other conditions have resulted in poor water quality, poor aquatic habitat, and negative visual impacts for park visitors. Planned improvements will address all of these issues utilizing best practices in stormwater treatment and water quality management.  As one of the park's few remaining historic features from the 1897 Tennessee Centennial Exposition, and one of the park's most popular destinations today, this project will make Lake Watauga more beautiful and more sustainable.
