Summary

This dam serves a primary purpose of recreation, providing a picturesque setting for water resource and climate enthusiasts to enjoy. With a hydraulic height of 18 feet and a structural height of 30 feet, Lochmere Lake Dam #2 has a storage capacity of 196 acre-feet and covers a surface area of 16.3 acres.

Despite its satisfactory condition assessment as of December 2019, Lochmere Lake Dam #2 has been classified with a high hazard potential, highlighting the importance of regular inspections and maintenance. The dam is regulated by the North Carolina Department of Environmental Quality's Dam Safety Program, ensuring that state permitting, inspection, and enforcement measures are in place to protect the surrounding community. While no specific spillway type or outlet gates are noted, the dam's construction along Long Branch stream provides both recreational opportunities and a critical water resource management function for the area.

As water enthusiasts continue to appreciate Lochmere Lake Dam #2 for its recreational value, it is crucial to recognize the broader implications of its role in water resource management and climate resilience. By staying informed about the dam's condition, maintenance, and regulatory oversight, enthusiasts can advocate for the sustainable management of this important infrastructure to ensure its long-term viability and safety for both recreational and environmental purposes.

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.
