Summary
This earth dam with a buttress core type stands at a height of 18 feet, providing a storage capacity of 63 acre-feet. The dam serves primarily for recreational purposes and is regulated, inspected, and enforced by the state agency, ensuring its safety and compliance with regulations.
With a low hazard potential and a moderate risk assessment rating, Swayze Lake Number 4 Dam is considered to be in satisfactory condition, although it has not been rated recently. The dam features an uncontrolled spillway type and has no associated locks or outlet gates. Despite its limited inspection frequency and lack of emergency action plan assessment, the dam's risk management measures are not specified, indicating a need for further evaluation and preparedness measures to ensure safety and protection of the surrounding community and environment.
Water resource and climate enthusiasts interested in Swayze Lake Number 4 Dam can appreciate its unique design and purpose, as well as the regulatory oversight provided by the state agency. The dam's location within the Vicksburg District offers opportunities for outdoor recreation and enjoyment, while its storage capacity and hydraulic features contribute to the local hydrological landscape. Continued monitoring and assessment of the dam's condition and risk management measures are essential to maintain its integrity and safety for both recreational users and the surrounding area.

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.
