Willoway Upground No. 5 Dam dam
Willoway Upground No. 5 Dam
The Willoway Upground No. 5 Dam, located in Avon, Ohio, was completed in 1999 and serves as a vital water supply structure in the region. Owned by a private entity, this earth-type dam stands at a height of 12 feet and has a length of 2440 feet, with a storage capacity of 71 acre-feet. The dam is situated on the Slater Ditch, with a drainage area of 0.01 square miles, providing essential water resources for the community.
Managed by the Department of Natural Resources in Ohio, the Willoway Upground No. 5 Dam is subject to regular state inspections, with the last assessment conducted in September 2018, revealing satisfactory conditions. Despite its high hazard potential, the dam is well-maintained and meets regulatory guidelines for water resource management. The dam's Emergency Action Plan (EAP) was last revised in June 2020, ensuring readiness for any unforeseen events or emergencies.
Enthusiasts of water resources and climate will find the Willoway Upground No. 5 Dam a significant part of the infrastructure in Lorain County, Ohio. With its crucial role in water supply and its adherence to state regulations, this dam stands as a testament to responsible management of resources in the face of changing environmental conditions.
Dam data reference
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 Willoway Upground No. 5 Dam
Where does the data for Willoway Upground No. 5 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.
