Summary

Completed in 1977, this earth dam stands at a height of 14 feet and has a hydraulic height of 10 feet. With a storage capacity of 217 acre-feet, the dam serves as a vital resource for the surrounding area, providing essential water storage for recreational activities and wildlife habitat.

Managed by the Department of Conservation and Recreation, Crooked Pond Dam has a significant hazard potential, but its condition assessment in 2017 deemed it satisfactory. The dam's Emergency Action Plan (EAP) was last revised in May 2018, indicating ongoing efforts to ensure public safety in case of emergencies. Despite moderate risk assessment, the dam's risk management measures and inundation maps preparation status remain unclear, warranting continued monitoring and assessment.

With a drainage area of 0.4 square miles and a surface area of 1364 acres, Crooked Pond Dam plays a crucial role in maintaining the local ecosystem and providing recreational opportunities for visitors. Its association with Windsor Pond Brook highlights its importance in the broader watershed context, making it a key feature for water resource and climate enthusiasts interested in the conservation and management of Massachusetts' water infrastructure.

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.
