Equinus (Legendary Run) Lake Dam dam
Equinus (Legendary Run) Lake Dam
Equinus (Legendary Run) Lake Dam, located in Clermont, Ohio, is a privately owned Earth dam completed in 2001 for water supply purposes. Standing at a height of 45.3 feet, with a length of 280 feet, the dam has a storage capacity of 78 acre-feet and a normal storage of 49 acre-feet. The dam is situated in the Ohio River city and is regulated by the Department of Natural Resources in Ohio.
With a high hazard potential, the dam has been assessed to be in satisfactory condition as of April 2018. Regular inspections are conducted every 5 years to ensure its safety and integrity. The dam's primary purpose is to serve as a water supply source, with a drainage area of 0.17 square miles and a maximum discharge capacity of 1689 cubic feet per second.
Despite being a private structure, Equinus (Legendary Run) Lake Dam plays a crucial role in water resource management in the region. Its construction and management are vital for ensuring a stable water supply and mitigating potential hazards associated with its operation. Enthusiasts of water resources and climate will find this dam's design and functionality intriguing in the context of sustaining water availability in the area.

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 Equinus (Legendary Run) Lake Dam
Where does the data for Equinus (Legendary Run) Lake Dam 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 High 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.
