The original dam was a timber crib structure, consisting of an outside frame of timbers filled with dirt and rock, and the original lock was stone masonry. The structures are located one hundred and seventeen miles above the mouth of the Ohio River.

The three generators of the 1928 hydropower plant quit producing power in 1999.
"The hydroelectric plant is named “Mother Ann Lee Hydroelectric Station,” after the founder of the Shakers, a religious sect known for ingenuity in the 1800s."
New owners got it running again in 2007-08 and certified as a "low-impact" plant.
Unfortunately, a web page that is supposed to have a photo gallery is empty.

Kentucky Utilities, who was the owner in 1999 filed a plan to remove the power plant. The plan received a lot of pushback from the public. Thus they were motivated to sell it in 2005 to a corporation that was formed to rehabilitate the powerhouse.
The powerhouse is built on top of three piers. Each pier contains a 40' shaft that connects a turbine in the dam to a generator in the powerhouse. Even so, the powerhouse was flooded during the record flood of 1978.
The river had dissolved oxygen issues and the turbines were modified to improve the DO levels. They also offer tours as part of an education program. The fish paintings were done by a local 4th grade class.
