Summary
Completed in 1944, this earth dam stands at a hydraulic height of 8 feet and a structural height of 10 feet, with a length of 636 feet. The dam has a normal storage capacity of 48 acre-feet and a maximum storage of 58 acre-feet, serving as a vital resource for water management in the area.
Situated on the Little Coharie Creek-Tr, Mclamb Lake Dam has a low hazard potential and has not been rated for its condition since its last inspection in 2008. Despite not being regulated by the state, the dam is subject to regular inspections to ensure its safety and integrity. While it does not have associated structures or spillway features, the dam plays a crucial role in irrigation and recreation activities in the Clear Run community.
With a history dating back to the mid-20th century, Mclamb Lake Dam continues to play a significant role in water resource management in the region. While it may not be subject to strict state regulations, the dam's importance in irrigation and recreational activities underscores the need for continued monitoring and maintenance to ensure its long-term functionality and safety for the surrounding community.

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.
