Summary

With a height of 18.5 feet and a storage capacity of 175.16 acre-feet, this dam plays a vital role in water resource management in the area. Despite its undetermined hazard potential and lack of a formal condition assessment, the dam remains a key feature in the local landscape and continues to provide valuable water storage for the community.

The dam, completed at an unspecified date, stands at a length of 280 feet and has a surface area of 16.6 acres. While details about its spillway type and maximum discharge are not available, the dam's importance in managing water flow and storage cannot be overstated. Situated in a picturesque location with a latitude of 37.5648 and longitude of -76.4966, Healys Mill Dam is not only a functional structure but also a point of interest for water resource and climate enthusiasts in the region.

Although the dam's emergency action plan and risk assessment information are not provided, its presence as a regulated and inspected structure underscores the commitment to maintaining its integrity and ensuring the safety of downstream communities. With the Norfolk District overseeing its management, Healys Mill Dam stands as a testament to the intersection of human ingenuity and environmental stewardship in balancing water resource needs with public safety considerations.

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.
