Summary
3 Dam, located in Duncanwood, Ohio, was completed in 1982 by the Consolidation Coal Company for the primary purpose of storing tailings. This privately owned earth dam stands at a height of 54 feet and spans a length of 280 feet, with a storage capacity of 3,290 acre-feet. Situated along a tributary to South Fork, the dam is regulated by the Ohio Department of Natural Resources and undergoes regular inspections to ensure its structural integrity.
With a significant hazard potential, Dickerson Slurry No. 3 Dam poses a risk that necessitates emergency preparedness and risk management measures. However, the dam's condition assessment is currently not rated, highlighting the need for ongoing monitoring and maintenance to prevent potential failures. Despite its age, the dam has not been modified in recent years and lacks detailed information on its emergency action plan and risk assessment, indicating a need for further evaluation and improvements in its safety protocols.
For water resource and climate enthusiasts, Dickerson Slurry No. 3 Dam serves as a fascinating case study in dam construction and management. Its location in Harrison County, Ohio, offers a unique opportunity to study the interactions between human-made structures and natural water systems, providing valuable insights into the challenges and opportunities in ensuring the safety and sustainability of our water resources in the face of 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.
