Summary
The dam, situated on White Cypress Creek, serves primarily for recreational purposes, offering a serene escape for water resource and climate enthusiasts. With a low hazard potential and moderate risk assessment, the dam provides a safe environment for visitors to enjoy the 62.15-acre storage and 14.8-acre surface area.
Constructed as an earth dam with a buttress core type, Necaise Lake Dam stands at a height of 7 feet with an uncontrolled spillway type. Despite not having a structural assessment rating, the dam's condition is deemed as "Not Rated," indicating a need for further evaluation to ensure its long-term stability. The dam's risk management measures and emergency action planning are not specified, underscoring the importance of ongoing maintenance and monitoring to mitigate potential risks.
Although Necaise Lake Dam may not be as well-known as other larger dams, its peaceful surroundings and recreational offerings make it a hidden gem for those interested in water resources and climate. As an integral part of the local landscape, the dam serves as a reminder of the delicate balance between human development and environmental stewardship, highlighting the importance of responsible dam ownership and management in the face of changing climate conditions.

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.
