Summary
This rockfill dam, completed in 1900, stands at a height of 10 feet and has a storage capacity of 540 acre-feet, with a normal storage level of 420 acre-feet. The pond covers an area of 170 acres and is fed by the Haley Pond Outlet.
Despite being in fair condition as of the last assessment in 2015, the dam at Haley Pond is classified as having a significant hazard potential. Regular inspections every 6 years ensure its safety and integrity, with the last one conducted in August 2016. The dam's Emergency Action Plan (EAP) was last reviewed in September 2020, highlighting the commitment to preparedness in case of an emergency.
Haley Pond offers a tranquil setting for water resource and climate enthusiasts to appreciate the interplay between human infrastructure and natural ecosystems. Its role in flood risk reduction, wildlife habitat, and recreational activities underscores the importance of responsible dam management in maintaining the delicate balance between conservation and development in the region.

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.
