LAKE GUNTERSVILLE, Ala.  — Greenway users will be seeing drilling equipment on Guntersville Dike and Guntersville Dam over the next several weeks as the Tennessee Valley Authority conducts a geotechnical evaluation of the facility and surrounding area as part of a health check update of all 49 dams in the TVA system.

TVA’s dams are safe, and the health check is part of a continuous improvement program to make sure TVA’s dams meet today’s stringent industry safety standards.

As part of the Guntersville Dam and Dike health check, TVA anticipates that core drilling from the greenway on the dike will require some closures and minor inconvenience.

The approximate duration of the closure will be about two months.

The public is urged to watch for construction workers and equipment, and to be cautious when approaching the work zone on the dike’s greenway. All scheduled work is subject to change depending on weather, geotechnical conditions encountered and other factors.

Construction of Guntersville Dam began in 1935 and was completed in 1939.

The dam is 94 feet high and stretches 3,979 feet across the Tennessee River.

Guntersville Dam is a hydroelectric facility. It has four generating units with a net dependable capacity of 124 megawatts. Net dependable capacity is the amount of power a dam can produce on an average day, minus the electricity used by the dam itself.

Guntersville Reservoir has almost 890 miles of shoreline and 67,900 acres of water surface.

The Tennessee Valley Authority is a corporate agency of the United States that provides electricity for business customers and local power distributors serving 9 million people in parts of seven southeastern states. TVA receives no taxpayer funding, deriving virtually all of its revenues from sales of electricity. In addition to operating and investing its revenues in its electric system, TVA provides flood control, navigation and land management for the Tennessee River system and assists local power companies and state and local governments with economic development and job creation.
