The Radnor Lake Industrial Complex was built by the Louisville & Nashville Railroad Company in the 1910s. It consists of the lake, the dam, approximately four miles of pipe, the caretaker’s residence, and most importantly the main valve. A railroad employee was assigned to live in the caretaker’s residence (click here for more information about the caretakers). They were responsible for opening and closing the main valve as well as overseeing the property. The main valve sits below the dam and was used to control the flow of water from Radnor Lake to Radnor Yards nearly four miles away. At the height of its use, Radnor Lake provided 1,000,000 gallons of water a day to the rail yards. This water was used by the railroad for steam engines and for cattle to drink.

In recent years Radnor Lake staff have partnered with Middle Tennessee State University (click here to find out more about MTSU’s research projects) to preserve the industrial complex at Radnor Lake and to provide interpretive signage for visitors to the park. The industrial complex has been registered as an archeological site (40DV635).
