Summary
Built in 1811, this Earth-type dam stands at an impressive height of 12 feet and spans a length of 400 feet. With a storage capacity of 114 acre-feet, Pigeon Brook serves as a vital water resource for the surrounding area, covering a drainage area of 1.7 square miles.
Despite its historical significance and recreational value, Pigeon Brook poses a significant hazard potential due to its poor condition assessment as of June 2017. The dam's last inspection was conducted in 2017, with a mandated inspection frequency of 6 years. With its proximity to the Pigeon River and stream, the dam's structural integrity and maintenance are crucial for preventing potential risks and ensuring the safety of the surrounding community.
As water resource and climate enthusiasts, the data on Pigeon Brook highlights the importance of maintaining and monitoring aging infrastructure to mitigate risks and protect valuable water resources. With its significant hazard potential and poor condition assessment, proper risk management measures and regular inspections are essential for safeguarding the dam and the environment it serves. The involvement of regulatory agencies such as MEMA in permitting, inspecting, and enforcing safety protocols underscores the collaborative effort needed to address potential vulnerabilities and ensure the long-term sustainability of water resources like Pigeon Brook.

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.
