Completed in 2004, this privately owned Earth type dam serves the primary purpose of tailings management, with a hydraulic height of 15.2 feet and a structural height of 23.3 feet. The dam has a storage capacity of 1110 acre-feet, with a normal storage level of 563 acre-feet, covering a surface area of 81.3 acres and draining a 1.65 square mile watershed.
Managed by the Mississippi Department of Environmental Quality, the Sp-4 Dam holds a low hazard potential and a moderate risk assessment rating. It features an uncontrolled spillway and outlet gates, ensuring efficient water discharge during peak flows. With a regulated state jurisdiction and inspection, the dam plays a crucial role in flood control and environmental protection along the UNT of Middle Bywy Creek. Despite its significant contributions, the dam's condition assessment remains unrated, highlighting the need for ongoing monitoring and maintenance efforts to uphold its structural integrity and safeguard surrounding communities from potential risks.
