Summary
The dam, primarily used for recreation, is of Earth construction type and stands at a height of 8 feet with a hydraulic height of 6 feet. The pond has a maximum storage capacity of 34 acre-feet and a normal storage level of 25 acre-feet. With a surface area of 8 acres and a spillway width of 12 feet, Stone Pond offers a serene setting for outdoor enthusiasts to enjoy various water activities.
Despite its scenic appeal, Stone Pond poses a high hazard potential due to its poor condition assessment. The last inspection in 2017 revealed the dam's structural deficiencies, leading to a heightened risk of potential failure. Emergency action plans are either non-existent or outdated, raising concerns about the pond's ability to withstand unforeseen events. With a high hazard potential and poor condition assessment, Stone Pond requires immediate attention and proactive risk management measures to ensure the safety of surrounding communities and the preservation of this valuable water resource.
Given its high hazard potential and poor condition assessment, Stone Pond serves as a critical case study for water resource and climate enthusiasts. The dam's structural integrity and emergency preparedness protocols are vital components in mitigating potential risks associated with climate change and extreme weather events. Through collaborative efforts between state regulatory agencies and private owners, Stone Pond can be safeguarded for future generations to enjoy, while also serving as a model for sustainable water management practices in the face of environmental uncertainties.

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.
