Grenke Lake Dam dam
Grenke Lake Dam
Located in Eagleville, Ohio, Grenke Lake Dam is a privately owned structure managed by the Department of Natural Resources. This earth dam stands at 16.4 feet high and spans 400 feet in length, creating a reservoir with a storage capacity of 75.7 acre-feet. The primary purpose of this dam is for recreation, providing opportunities for fishing, boating, and other water-based activities in the area.
Despite its low hazard potential, Grenke Lake Dam is currently assessed as being in poor condition as of the last inspection in May 2016. The dam's emergency action plan status and risk assessment measures are unclear, raising concerns about its ability to withstand potential incidents or extreme weather events. With a drainage area of 0.81 square miles and a maximum discharge capacity of 174 cubic feet per second, the dam plays a critical role in managing water resources and protecting downstream areas from flooding.
As water resource and climate enthusiasts continue to monitor Grenke Lake Dam, there is a need for enhanced maintenance and risk management measures to ensure its long-term integrity and safety. With its recreational importance and role in flood control, addressing the dam's poor condition and implementing necessary improvements will be essential for protecting both the local community and the surrounding environment from potential water-related risks.

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 Grenke Lake Dam
Where does the data for Grenke 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 Low 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.
