Summary
Constructed in 1898, this Earth-type dam stands at a height of 13 feet and spans 625 feet, with a primary purpose of providing recreational opportunities for enthusiasts. The dam boasts a storage capacity of 93 acre-feet, with a normal storage level of 48 acre-feet, covering a surface area of 15 acres.
Despite its historical significance and recreational value, Singletary Millpond faces challenges in terms of its condition assessment, which has been deemed poor as of the last inspection in November 2017. The dam has a low hazard potential but is considered to have a very high risk level, indicating a need for improved risk management measures. While the dam is state-regulated and undergoes regular inspections, the current state of its condition raises concerns for water resource and climate enthusiasts who value the preservation and safety of such structures. Efforts to address these concerns and enhance the resilience of Singletary Millpond may be crucial in ensuring its long-term sustainability and continued recreational use.

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.
