1 Dam, also known as Parksville Lake, is a concrete dam located on the Ocoee River in Polk, Tennessee. Built in 1911 by TN Electric Power, this dam stands at a height of 127 feet and has a structural height of 135 feet. It serves multiple purposes, including flood risk reduction, hydroelectric power generation, and recreation, with a normal storage capacity of 79,320 acre-feet.
Managed by the Tennessee Valley Authority (TVA), Ocoee No. 1 Dam has a high hazard potential due to its proximity to populated areas. The dam has undergone several modifications over the years, with the most recent in 1975 to enhance its structural integrity. Despite its age, the dam is regularly inspected by TVA to ensure its safety and reliability, with the last inspection conducted in March 2021.
With a drainage area of 595 square miles and a maximum discharge capacity of 26,620 cubic feet per second, Ocoee No. 1 Dam plays a crucial role in managing water resources in the region. Its strategic location and design make it a significant asset for flood control, energy production, and recreational activities along the Ocoee River.
