Summary
With a height of 12 feet and a length of 150 feet, the dam has a storage capacity of 173 acre-feet and a surface area of 17 acres. It has a high hazard potential and a poor condition assessment, last inspected in January 2020 with a frequency of every 2 years.
Managed by the New York State Department of Environmental Conservation, the dam features an uncontrolled spillway with a width of 10 feet and a maximum discharge of 160 cfs. Located in Rensselaer County, the dam's risk assessment is moderate, with no emergency action plan prepared as of the last update in 2010. Despite its poor condition, the dam continues to serve its primary purpose of recreation in the area.
Water resource and climate enthusiasts interested in Mill Pond Dam can explore its historical significance as a recreational structure while considering its maintenance and risk management measures. The dam's location on the TR-QUACKEN KILL stream adds to its ecological importance, highlighting the intersection of human infrastructure with natural water systems in the region. As efforts to mitigate risks and ensure public safety continue, the future of Mill Pond Dam remains a topic of interest for those invested in sustainable water resource management and climate resilience.

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.
