Summary
Built in 1920, this dam stands at a height of 7 feet and has a storage capacity of 2,685 acre-feet, with a normal storage level of 2,238 acre-feet. The dam spans 160 feet in length and covers a surface area of 192 acres, drawing water from the Jordan Stream.
Managed by the Maine Emergency Management Agency (MEMA), Jordan Pond is state-regulated, with permitting, inspection, and enforcement measures in place to ensure its safe operation. Despite its low hazard potential, the dam's condition assessment remains unrated, highlighting the need for ongoing monitoring and maintenance to uphold its integrity. With a designated emergency action plan (EAP) yet to be prepared, there is room for improvement in risk management and response protocols for this essential water resource.
Water resource and climate enthusiasts will find Jordan Pond to be a fascinating structure that plays a critical role in providing water supply to the surrounding area. As a concrete dam with a long history and a capacity to withstand low hazard levels, it represents a key piece of infrastructure that requires careful oversight and maintenance to ensure continued safe operation. With its location in the picturesque landscape of Hancock, Maine, Jordan Pond serves as a reminder of the intersection between human engineering and natural beauty, making it a noteworthy site for those interested in the intersection of water management and environmental conservation.

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.
