Summary
Built in 1900 for hydroelectric purposes, this dam stands at 26 feet in height and spans 1800 feet in length, with a storage capacity of 100 acre-feet. Despite its age, the dam has a low hazard potential and has been inspected by the Federal Energy Regulatory Commission, meeting safety guidelines.
The surrounding area of Mayodan benefits from the controlled spillway and the dam's ability to manage a maximum discharge of 220 cubic feet per second. The risk assessment for Avalon - Canal Embankment is marked as very high, emphasizing the importance conditions and management measures. With a notable risk level of 1, concerns may arise, but the dam's emergency action plan (EAP) was last revised in December 2020, suggesting proactive measures in place for potential hazards.
As a crucial part of the local water infrastructure, the Avalon - Canal Embankment stands as a reminder of the region's rich hydroelectric history. With its operational inspections and controlled spillway design, this dam continues to serve its purpose while maintaining a low hazard potential despite its age. Ongoing risk assessments and emergency preparedness ensure the safety and integrity of this water resource for the community of Mayodan and beyond.

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.
