Summary
Standing at a height of 22.2 feet and stretching 644 feet in length, the dam boasts a storage capacity of 373 acre-feet and covers a surface area of 25.9 acres. Despite its low hazard potential, the dam is regulated by the Mississippi Department of Environmental Quality and undergoes regular inspections, enforcement, and permitting to ensure its safety and compliance with state regulations.
The dam features an uncontrolled spillway and is classified as a buttress dam. While its condition assessment is currently not rated, the risk assessment for Massey Dam is considered moderate. The dam does not have an Emergency Action Plan in place, but it meets state guidelines and has designated emergency contacts. Overall, Massey Dam presents an intriguing case study for water resource and climate enthusiasts due to its unique design, recreational purpose, and regulatory oversight in the state of Mississippi.
With its picturesque location and important role in local recreation, Massey Dam serves as a focal point for water management discussions in the region. Despite its moderate risk assessment, the dam's low hazard potential and regular monitoring demonstrate a commitment to safety and environmental protection. As climate change continues to impact water resources, the management and maintenance of dams like Massey Dam will be crucial in ensuring the sustainability and resilience of our water infrastructure in the face of evolving climate challenges.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
