Summary

This earth dam, built on Mill Creek, serves primarily for irrigation purposes, with a hydraulic height of 11 feet and a structural height of 15 feet. The dam has a normal storage capacity of 26 acre-feet, covering a surface area of 6 acres and draining a watershed of 397 acres.

Despite its important role in providing water for irrigation, the Longleaf Golf Course Dam has been flagged as having a high hazard potential and poor condition assessment. The last inspection in February 2021 revealed these concerning findings, prompting a biennial inspection frequency to monitor its safety. Emergency action plans have been mentioned, but details on their preparation and compliance with guidelines remain unclear. It is crucial for authorities and stakeholders to address the dam's structural integrity and potential risks to ensure the safety of surrounding communities and the environment.

As climate change continues to impact water resources and extreme weather events become more frequent, the maintenance and management of dams like Longleaf Golf Course Dam are essential. With the potential for increased flood risks and the need for sustainable water management practices, it is imperative to prioritize the safety and resilience of such critical infrastructure. Collaboration between private owners, regulatory agencies, and the community is key to safeguarding water resources and adapting to a changing climate for a more sustainable future.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
