Summary
This earth-type dam, with a height of 10.2 feet and a hydraulic height of 8 feet, plays a crucial role in maintaining a normal storage capacity of 24.6 acre-feet and a surface area of 8.37 acres. The dam is regulated by the Department of Conservation and Recreation, ensuring that it meets state inspection and enforcement standards for safety and environmental protection.
The dam's significant hazard potential is addressed through regular inspections, with its condition assessed as satisfactory as of January 2014. Despite its moderate risk level, the dam's risk management measures and emergency action plan status are not updated, indicating a potential area for improvement. With a drainage area of 1.58 square miles and a storage capacity of 38.6 acre-feet, Mill Pond Dam plays a critical role in supporting aquatic ecosystems and recreational activities in the region.
As an integral part of the Island Creek watershed, Mill Pond Dam not only contributes to the local fish and wildlife habitat but also provides opportunities for recreation. With its strategic location and importance in water resource management, the dam serves as a reminder of the interplay between human infrastructure and natural ecosystems, highlighting the need for sustainable practices in safeguarding our water resources amidst changing climate conditions.

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.
