Summary

Built in 1979, this privately owned earth dam serves a primary purpose of recreation, offering a serene escape for visitors to enjoy the beauty of Beaverdam Swamp-Os. With a structural height of 23 feet and a hydraulic height of 20 feet, the dam spans 540 feet in length and holds a maximum storage capacity of 92 acre-feet.

Despite its low hazard potential, Crumpler Lake Dam is not regulated by the state and has not been rated for its condition since its last inspection in 2012. The dam's normal storage capacity of 80 acre-feet covers a surface area of 10 acres, serving as a vital resource for the surrounding community. As climate change continues to impact water resources, the importance of maintaining and monitoring structures like Crumpler Lake Dam becomes increasingly critical to ensure the safety and sustainability of these essential resources for future generations.

With its idyllic setting and recreational opportunities, Crumpler Lake Dam stands as a reminder of the delicate balance between human intervention and environmental stewardship. As water resource and climate enthusiasts continue to advocate for responsible management practices, structures like this provide a tangible example of the intersection between human development and natural ecosystems. As we navigate the challenges of a changing climate, Crumpler Lake Dam serves as a beacon of hope, showcasing the potential for harmonious coexistence between humans and the environment.

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.
