Brown's Lake Dam in Vicksburg, Mississippi, built in 1930 by the US Army Corps of Engineers, serves as a water supply source for the area with a storage capacity of 100 acre-feet.

The dam, primarily made of earth and stone, stands at a height of 27 feet and has a spillway width of 99 feet. Though the risk assessment in 2020 classified it as a Dam Safety Action Classification (DSAC) 4 due to concerns of overtopping and internal erosion, the risk of failure is considered low, with minimal impact on life and critical infrastructure downstream.
To mitigate potential risks, the USACE conducts periodic inspections to monitor seepage and dam stability. However, with the dam no longer serving its original purpose, plans for decommissioning are underway in fiscal year 2023, pending funding availability. This proactive approach aims to address any safety concerns and evaluate the long-term viability of the structure, ensuring the safety of surrounding communities and infrastructure in the event of a flood or breach. Water resource and climate enthusiasts can appreciate the diligent risk management measures being implemented to safeguard the area's water supply and residents.
