Summary

This recreational dam stands at a hydraulic height of 11 feet and a structural height of 15 feet, with a length of 600 feet. It serves the primary purpose of recreation, offering a serene environment for water resource and climate enthusiasts to enjoy nature.

With a storage capacity of 134 acre-feet, Boone Millpond Dam plays a significant role in managing water resources in the area. Despite not being state-regulated, the dam is inspected regularly, with the last assessment conducted in October 2003. The dam is classified as having a significant hazard potential, although its condition is currently not rated.

For those interested in water resource management and climate resilience, Boone Millpond Dam presents an intriguing case study of a historic earth dam providing recreational opportunities while also serving as a crucial infrastructure element in the region's water management system. Its location on the Gumberry Swamp adds to its ecological significance, making it a valuable asset for both local residents and visitors seeking to connect with nature in North Carolina's Northampton County.

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.
