Summary

Bartlett and completed in 1947. The dam stands at a height of 19 feet and has a hydraulic height of 11 feet, serving primarily for fish and wildlife pond maintenance and irrigation purposes. With a storage capacity of 130 acre-feet and a surface area of 11 acres, Long Pond plays a crucial role in water resource management in the area.

Although the dam's hazard potential is categorized as low, its condition assessment is marked as poor, raising concerns about its long-term stability and effectiveness. The spillway type is uncontrolled, with a width of 60 feet, and the outlet gates consist of a single valve. The last inspection of the dam was conducted in August 2018, with an inspection frequency of 5 years, indicating a need for ongoing maintenance and monitoring to ensure its structural integrity and safety.

Overall, Long Pond serves as a vital water resource infrastructure for irrigation and wildlife conservation in the region. However, with its poor condition assessment and moderate risk level, stakeholders must prioritize maintenance and risk management measures to safeguard the dam's functionality and prevent potential hazards in the future.

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.
