Fortney Lake Dam dam
Fortney Lake Dam
Fortney Lake Dam, located in Darbyville, Ohio, is a privately owned earth dam completed in 1960 for recreational purposes. The dam stands at a height of 15.4 feet and spans a length of 580 feet, creating a reservoir with a normal storage capacity of 27.6 acre-feet. Situated on a tributary to Big Darby Creek, the dam is regulated by the Ohio Department of Natural Resources and undergoes regular inspections to ensure its structural integrity.
Despite its low hazard potential and satisfactory condition assessment, Fortney Lake Dam plays a crucial role in maintaining the water resources and recreational opportunities in Pickaway County, Ohio. With a maximum discharge capability of 644 cubic feet per second, the dam serves as a vital component of the local watershed management system. Furthermore, its location within the Louisville District of the US Army Corps of Engineers underscores the importance of proper maintenance and oversight to mitigate potential risks associated with dam failure.
Given its significance in the region's water infrastructure, Fortney Lake Dam serves as a prime example of the intersection between water resource management and climate resilience. As climate change continues to impact precipitation patterns and water availability, the proper regulation and maintenance of dams like Fortney Lake become increasingly crucial for ensuring water security and disaster preparedness in the face of evolving environmental challenges.

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 Fortney Lake Dam
Where does the data for Fortney 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.
