Summary
2 Slurry Pond, also known as Perkins Run, is a private water supply structure located in Alledonia, Belmont County, Ohio. This Earth-type dam stands at a towering height of 300 feet and spans 7,050 feet in length, with a storage capacity of 3,131 acre-feet. While not regulated by the state, this high-hazard potential dam is overseen and inspected by the Mine Safety and Health Administration. Despite its critical role in water supply, the dam's condition assessment is currently not available, highlighting potential risks and challenges in its maintenance.
With a primary purpose of water supply and additional functions for tailings management, No. 2 Slurry Pond plays a vital role in supporting local water needs. Located just 2.5 miles away from the city, this structure is crucial for maintaining a reliable water source in the region. Although lacking detailed information on its inspection frequency and emergency preparedness, the dam's significant storage capacity and high hazard potential underscore the importance of ensuring its safety and stability for both water resource and climate enthusiasts in the area.
As a privately owned structure with no state jurisdiction or permitting requirements, No. 2 Slurry Pond stands as a key component of the local water infrastructure, providing essential storage and supply capabilities. Despite its remote location and limited regulatory oversight, the dam's impressive height and storage capacity demand attention and careful monitoring to mitigate potential hazards and ensure continued water resource availability for the community. For water resource and climate enthusiasts, this structure serves as a focal point for understanding the intersection of infrastructure, regulatory oversight, and environmental stewardship in maintaining a sustainable water supply system.

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.
