Summary
Standing at a structural height of 23 feet and a length of 400 feet, the dam serves as a vital structure along the Rocky Marsh Creek. With a primary purpose classified as "Other," the dam has a normal storage capacity of 8 acre-feet and a maximum storage of 10 acre-feet.
Despite not being state-regulated, Mclamb Lagoon Dam poses a significant hazard potential and has not been rated for its condition since the last inspection in May 2012. The dam's emergency action plan status, risk assessment, and inundation maps preparedness remain unclear. The dam's location, surrounded by natural beauty, draws attention to the importance of proper maintenance and monitoring to ensure the safety of the surrounding community and water resources.
As a key feature in the water resource infrastructure of the region, Mclamb Lagoon Dam serves as a reminder of the intersection between human development and environmental stewardship. With its proximity to the Wilmington District and representation by David Rouzer in Congress, the dam's maintenance and safety are crucial considerations for both local authorities and climate enthusiasts alike. Efforts to enhance risk management measures and emergency preparedness for the dam will be essential to mitigate potential threats and safeguard the surrounding area's ecological balance.

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.
