Summary
Completed in 2000 by Greenwood Engineering, this earth dam stands at a height of 17.5 feet and spans 870 feet across the UNT of Yocona River. With a storage capacity of 109 acre-feet, the dam primarily serves recreational purposes, offering a surface area of 7.81 acres for water enthusiasts to enjoy.
Although the hazard potential of Rowsey Dam is currently undetermined and its condition is not rated, the risk assessment categorizes it as moderate. The dam's spillway type is uncontrolled, with a maximum discharge capacity of 1573 cubic feet per second. Despite the lack of outlet gates and associated structures, the dam's construction and maintenance fall under state jurisdiction, ensuring regular inspections and enforcement of safety regulations.
As a focal point for water resource and climate enthusiasts, Rowsey Dam presents an opportunity for recreation in the heart of Mississippi. With its serene surroundings and potential for outdoor activities, this buttress-type earth dam promises a tranquil escape for visitors seeking to immerse themselves in the beauty of nature.

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.
