Summary

Completed in 2013, this earth dam stands at a height of 20 feet and has a hydraulic height of 16 feet. With a primary purpose of recreation, the dam offers a storage capacity of 25.01 acre-feet and a surface area of 2.46 acres, making it an ideal spot for water resource and climate enthusiasts to explore.

The dam, situated on Pumpkin Hollow Brook, has a drainage area of 0.83 square miles and a normal storage capacity of 14.43 acre-feet. Although the hazard potential is deemed significant, the condition assessment as of April 2014 was satisfactory. With an inspection frequency of 5 years, the dam poses a moderate risk and has not been modified since its completion. The presence of an uncontrolled spillway adds to the recreational charm of the dam, attracting visitors to witness its engineering marvel.

Owned by a private entity, Conway Recreation Dam serves as a hub for outdoor activities and water-based adventures in Franklin County, Massachusetts. With its picturesque location and satisfactory condition, this dam presents a unique opportunity for water resource and climate enthusiasts to engage with nature while appreciating the importance of responsible dam management and regulation in safeguarding our environment.

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.
