About this dam

Four Eagles Lake Dam

Four Eagles Lake Dam, located in Preble, Ohio, stands as a vital piece of infrastructure designed by the Ralph L. Woolpert Co. in Dayton. Completed in 1959, this private dam serves primarily for recreational purposes, offering a serene retreat for water resource and climate enthusiasts alike. With a height of 45 feet and a length spanning 620 feet, the dam holds a storage capacity of 616 acre-feet, creating a surface area of 25.5 acres and draining over a 3.1 square mile area.

Maintained and regulated by the Department of Natural Resources in Ohio, Four Eagles Lake Dam poses a high hazard potential but has been assessed as satisfactory, with the last inspection taking place in April 2016. Its emergency action plan was last revised in June 2020, ensuring preparedness for any unforeseen events. With a maximum discharge capacity of 13,400 cubic feet per second, this earth dam ensures the safety and security of the surrounding community while providing a picturesque setting for outdoor activities.

As part of the Louisville District, Four Eagles Lake Dam is a testament to the intersection of human ingenuity and natural beauty. Its presence along Beasley Run not only enhances the local landscape but also serves as a reminder of the importance of proper water resource management in the face of changing climate patterns. For those passionate about water resources and climate sustainability, Four Eagles Lake Dam stands as a beacon of resilience and recreation in Ohio's countryside.

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.

FAQ

About Four Eagles Lake Dam

Where does the data for Four Eagles 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.
