Summary
Completed in 1937, this earth dam stands at a height of 31 feet and spans 385 feet in length, serving primarily as a water supply source. With a normal storage capacity of 163 acre-feet and a maximum storage of 361 acre-feet, the dam sits on the Manns Fork river, covering a surface area of 14.2 acres and draining an area of 2.46 square miles.
Managed by the Ohio Department of Natural Resources, the Blue Rock Lake Dam boasts a high hazard potential but is currently assessed to be in satisfactory condition based on the latest inspection in October 2020. The dam is regulated, permitted, inspected, and enforced by the state, ensuring proper maintenance and safety measures are in place. In case of emergencies, an Emergency Action Plan (EAP) is likely in place, although details on its preparedness and adherence to guidelines are not specified in the data.
For water resource and climate enthusiasts, the Blue Rock Lake Dam presents a fascinating case study of a key infrastructure supporting water supply in Ohio. Its historical significance, design features, and regulatory oversight provide valuable insights into the intersection of water management, dam safety, and environmental stewardship. As a vital component of the region's water infrastructure, the dam's role in ensuring water security and mitigating risks underscores the importance of sustainable water resource management practices in the face of changing climate dynamics.

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.
