Completed in 1972, this earth dam stands at a height of 56 feet with a length of 796 feet, providing a storage capacity of 400 acre-feet. The dam's spillway, with a width of 25 feet, is uncontrolled, and the outlet gates are operated by valves.
Despite being state-regulated and inspected, Lonedell Lake Dam has been assigned a high hazard potential due to its proximity to the TR to Tyrey Creek. However, the condition assessment in 2007 deemed the structure to be satisfactory, with a moderate risk assessment rating. The emergency action plan (EAP) for the dam was last revised in 2015, ensuring that adequate measures are in place for any potential incidents.
In the event of an emergency, the residents of RICHWOODS and surrounding areas can rest assured that Lonedell Lake Dam is equipped to handle any unforeseen circumstances. With its scenic location and recreational opportunities, this dam serves as both a vital water resource and a valuable asset for the community.
