Lake Waynoka Retention Dam dam
Lake Waynoka Retention Dam
Lake Waynoka Retention Dam, located in Arnheim, Ohio, is a vital water supply infrastructure designed by Robert C. Daniel and American Realty Service Corp. The dam, completed in 1973, stands at a height of 32.1 feet and stretches 370 feet in length, with a storage capacity of 296 acre-feet. Situated along Sycamore Run, the dam serves the primary purpose of water supply, providing a normal storage capacity of 89 acre-feet to the surrounding area.
Managed by the Department of Natural Resources in Ohio, Lake Waynoka Retention Dam is regulated, inspected, and enforced by state authorities to ensure its structural integrity and operational safety. With a significant hazard potential but a satisfactory condition assessment as of May 2018, the dam plays a crucial role in managing water resources and mitigating flood risks in the region. Its location in Brown County, Ohio, highlights its importance in maintaining a sustainable water supply for the community.
Despite its age, Lake Waynoka Retention Dam continues to meet the guidelines for emergency action plans, although updates to contact information and risk assessments may be necessary. With a history of successful operation and maintenance, the dam stands as a testament to effective water resource management in Ohio. Enthusiasts of water resources and climate resilience can appreciate the vital role that Lake Waynoka Retention Dam plays in safeguarding water supply and managing flood risks in the region.

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 Lake Waynoka Retention Dam
Where does the data for Lake Waynoka Retention 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 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.
