The dam, primarily constructed of earth with a stone core on a rock foundation, stands at a height of 20 feet and has a hydraulic height of 18 feet. With a storage capacity of 1340 acre-feet and a surface area of 52.6 acres, the dam plays a crucial role in supporting the local ecosystem and providing habitat for wildlife in the area.
Despite its low hazard potential, Dry Lake Dam is currently assessed as being in poor condition as of the last inspection in 2014. The dam has a very high risk level assigned, indicating the need for urgent risk management measures. With a drainage area of 29.3 square miles and a maximum discharge of 543 cubic feet per second, the dam's critical role in water resource management underscores the importance of ongoing monitoring and maintenance to ensure its structural integrity and safety for the surrounding community.
As a key structure within the Memphis District of the USACE, Dry Lake Dam's significance extends beyond its primary purpose as a Fish and Wildlife Pond. Its association with the La Grue Bayou and its vital role in water management make it a focal point for water resource and climate enthusiasts, highlighting the complex interplay between dams, ecosystems, and human activities in sustaining the delicate balance of our natural environment.
