Just a few weeks after this dam was finished, the "drawings, heavy equipment and seasoned engineers and construction workers" were used to build the
Douglas Dam. [

-- The dam is 175 feet high and stretches 6,760 feet, or well over a mile, from one end to the other.
-- In a year with normal rainfall, the water level in Cherokee Reservoir varies about 30 feet from summer to winter to provide seasonal flood storage. -- Cherokee has a flood-storage capacity of 749,400 acre-feet. -- Cherokee Dam is a hydroelectric facility. It has four generating units with a summer net dependable capacity of 122 megawatts. Net dependable capacity is the amount of power a hydroelectric dam can produce on an average day, minus the electricity used by the dam itself. |

Cherokee Dam, located on the Holston River in East Tennessee, began generating electricity 80 years ago!
This WWII-era dam does more than provide low-cost, renewable energy; it provides flood control, recreation, water supply, and much more.

Dennis DeBruler: I'm guessing the Cherokee Dam. |
After 80 years, the Unit 1 turbine was replaced by a turbine that can handle 30,872 gallons/sec and that can aerate the water. They have put the old turbine on display.

The giant spillway gates open at Cherokee Dam near Jefferson City, TN, releasing over 37,000 gallons of water per second as we recover flood storage. In less than a week, lake levels soared 7.8 feet because of heavy rainfall in the region. The last time we spilled at Cherokee was in 2013.
[That has to be 37,000 cubic feet per second. 37kgps is just 5kcfs.] |

Last time you spilled was September of 2018 |

On cold winter days, reliable megawatts are essential!
New upgrades and improvements on Unit 1 at Cherokee Dam will improve reliability, keeping American made megawatts flowing and your heat humming!⚡️🇺🇸
Additional improvements at Cherokee will increase the amount of clean energy the dam's four units can add to the electric grid.

A new 52-ton stainless steel Francis turbine runner is now in place at Cherokee Dam Unit 2—part of ongoing upgrades through our Hydro Life Extension Program.
Lifted into position by a massive crane, this modern aerating runner replaces the original and is designed to improve efficiency, increase generating capacity, and enhance downstream water quality by raising dissolved oxygen levels—benefiting both power reliability and aquatic life. 🐟⚡
It’s one more way we’re investing in the future of low-cost hydropower for the region.

I visited a Siemens facility in PA where they make these. Very impressive process. Everything is huge. |
