Echo, also known as Echo Lake Dam, is a privately owned structure located in Giles, Tennessee, along the Tributary Creek. Built in 1967 by the USDA NRCS, this Earth-type dam serves as a Fish and Wildlife Pond, providing crucial habitat for the local ecosystem. With a hydraulic height of 19.2 feet and a structural height of 22.2 feet, Echo has a storage capacity of 121 acre-feet and covers an area of 10 acres.

Managed by the Tennessee Safe Dams Program, Echo Dam is considered to have a significant hazard potential but is currently in satisfactory condition. Regular inspections are conducted by state authorities, with the last assessment taking place in August 2020. Despite its age, the dam meets safety guidelines and poses a moderate risk level. Its primary purpose of supporting fish and wildlife populations, along with recreational activities, highlights its importance in both conservation and community engagement within the region.

As a part of the Nashville District, Echo Dam stands as a testament to responsible water resource management in Tennessee. Its role in providing essential habitat for wildlife and supporting recreational opportunities underscores the importance of maintaining and monitoring such structures for the benefit of both the environment and the local community.
