Summary
Built in 1991, this earth dam stands at a structural height of 15.2 feet and has a hydraulic height of 12.2 feet, with a length of 660 feet. The dam holds a normal storage capacity of 11.4 acre-feet and has a maximum storage capacity of 150 acre-feet, covering a surface area of 1.7 acres.
Despite its low hazard potential and not being state-regulated, Malvin Harrington Pond Dam plays a crucial role in debris control and providing water supply for the area. The dam is situated on the Jacks Creek-Tr river/stream and is not under the jurisdiction of any state regulatory agency. Although the condition assessment of the dam is marked as 'Not Rated', it has undergone inspection as recently as May 2013. With no associated locks or spillways, the structure remains a key component in managing water resources for the local community.
Water resource and climate enthusiasts would find Malvin Harrington Pond Dam to be an intriguing example of a privately owned water supply infrastructure. With its construction aimed at fulfilling the purposes of debris control and water supply, the dam stands as a testament to the importance of maintaining and regulating such structures. While the dam's risk assessment and emergency preparedness details are not specified, its role in managing water resources in the region highlights the need for ongoing monitoring and maintenance to ensure its continued functionality and safety for the surrounding community.

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.
