Summary
Built in 2007 by KONECHNE ENG., this earth dam stands at 9 feet high and stretches 410 feet in length, with a storage capacity of 245 acre-feet. The dam is situated on TR CHAPELLE CREEK and serves the primary purpose of water resource management.
With a low hazard potential and a moderate risk assessment rating, Harter Pond Dam is currently considered to be in good condition, although its emergency action plan and risk management measures are not fully detailed. The spillway, which is uncontrolled and 80 feet wide, ensures the safe release of water when necessary. Despite not being rated for condition assessment, the dam has state permitting, inspection, and enforcement processes in place, highlighting its commitment to safety and compliance.
For water resource and climate enthusiasts, Harter Pond Dam presents a fascinating case study in dam infrastructure management. Its location in a rural area, combined with its relatively small size and low hazard potential, offers a unique perspective on the challenges and opportunities associated with maintaining and regulating a vital water resource in a remote setting. As climate change continues to impact water systems around the world, understanding the complexities of structures like Harter Pond Dam becomes increasingly important for ensuring the sustainability and resilience of our water resources.

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.
