Summary

With a height of 11 feet and a storage capacity of 1430 acre-feet, this dam plays a significant role in flood control and water resource management in the region. However, recent inspections have raised concerns about its condition, as it has been rated as poor and with a high hazard potential.

The dam, constructed for an unspecified primary purpose, has not been modified in recent years and lacks updated emergency action plans or risk assessments. Despite its critical role in the local water system, there is a pressing need for maintenance and potential rehabilitation to ensure the safety and effectiveness of Mclaurins Millpond Dam. With the last inspection conducted in September 2020 and a high hazard potential designation, stakeholders must prioritize the assessment and improvement of this essential water resource infrastructure to mitigate risks and safeguard surrounding communities from potential hazards.

As water resource and climate enthusiasts, it is crucial to monitor the status of structures like Mclaurins Millpond Dam to ensure their resilience in the face of changing environmental conditions. By advocating for proper maintenance, risk assessments, and emergency preparedness measures, we can contribute to the sustainable management of water resources and the protection of communities that rely on these critical infrastructure assets. Let's work together to address the challenges facing Mclaurins Millpond Dam and ensure its continued functionality for current and future generations.

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.
