Hunters Run Structure No. R-63 dam
Hunters Run Structure No. R-63
Hunters Run Structure No. R-63, also known as Greenfield Lake, is a local government-owned dam located in Fairfield, Ohio. Built in 1961 by the USDA NRCS, this earth dam serves as a crucial flood risk reduction measure on a tributary to the Hocking River. With a height of 29.7 feet and a length of 415 feet, the dam has a storage capacity of 210.8 acre-feet, making it a significant structure in the area.
Despite its importance in mitigating flood risks, Hunters Run Structure No. R-63 is currently assessed as being in poor condition as of its last inspection in May 2017. The dam is classified as having a significant hazard potential and a moderate risk level (3), emphasizing the need for regular maintenance and potential risk management measures. The dam's emergency action plan (EAP) status and adherence to guidelines remain unclear, highlighting the importance of ensuring preparedness and safety measures for this critical infrastructure.
With its location in a high-risk area and its outdated condition assessment, Hunters Run Structure No. R-63 serves as a reminder of the ongoing challenges faced in managing water resources and climate-related risks. As water resource and climate enthusiasts, staying informed and advocating for the necessary upkeep and improvements of such infrastructure is crucial for the safety and resilience of communities in the face of changing environmental conditions.

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 Hunters Run Structure No. R-63
Where does the data for Hunters Run Structure No. R-63 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.
