Horse Run No. 3 Dam Mb-40 dam
Horse Run No. 3 Dam Mb-40
Horse Run No. 3 Dam Mb-40, located in Unionville, Ohio, is a privately owned structure built in 1961 by the Ohio Power Company. This earth dam stands at a height of 42.2 feet and serves primarily for tailings storage purposes. With a storage capacity of 347.33 acre-feet, it plays a significant role in managing water resources in the area, particularly for the tributary to Horse Run.
The dam is regulated by the Department of Natural Resources in Ohio and undergoes regular inspections to ensure its safety and functionality. Despite being classified as having a significant hazard potential, its condition was assessed as fair during the last inspection in October 2018. The dam's emergency action plan status, risk assessment, and management measures are currently not available, highlighting areas for potential improvement in its overall risk management strategy.
For water resource and climate enthusiasts, Horse Run No. 3 Dam Mb-40 presents an intriguing case study in the intersection of human infrastructure and natural ecosystems. Its role in storing tailings and managing water flow in the region underscores the importance of sustainable dam management practices to mitigate risks and optimize water resource utilization. As efforts continue to enhance the dam's safety and emergency preparedness, it serves as a focal point for ongoing discussions on the resilience of water infrastructure in the face of climate change and increasing environmental challenges.
Dam data reference
Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Horse Run No. 3 Dam Mb-40
Where does the data for Horse Run No. 3 Dam Mb-40 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
