This gravity dam, primarily used for flood risk reduction, stands at a structural height of 47 feet with a hydraulic height of 39 feet. With a storage capacity of 277.3 acre-feet and a surface area of 17.93 acres, the dam plays a crucial role in managing water flow in the region.
Despite its low hazard potential, the South Side Detention Dam currently has a poor condition assessment and is in need of maintenance. The last inspection conducted in August 2020 revealed the dam's deteriorating state, prompting concerns about its long-term effectiveness. With an inspection frequency of 5 years and a moderate risk level assigned, there is a pressing need for rehabilitation efforts to ensure the dam's continued functionality and safety for the surrounding community.
As a key player in flood risk reduction in the area, the South Side Detention Dam serves as a vital infrastructure piece in the region's water resource management. With its historical significance and importance in safeguarding against potential flooding events, it is essential that proper maintenance and rehabilitation measures are implemented to uphold the dam's integrity and protect the local environment and communities from water-related risks.
