Roundup Lake Dam dam
Roundup Lake Dam
Located in Portage County, Ohio, Roundup Lake Dam is a privately owned structure with a primary purpose of recreation. Completed in 1949, this earth dam stands at a height of 12.4 feet and spans 860 feet in length, creating a reservoir with a storage capacity of 188 acre-feet. Situated on a tributary to Aurora Branch, the dam is regulated by the Department of Natural Resources and undergoes regular inspections to ensure public safety.
With a hazard potential rated as significant and a fair condition assessment as of the last inspection in May 2018, Roundup Lake Dam is a vital component of the local water resource infrastructure. Its normal storage capacity of 94 acre-feet supports recreational activities for visitors to the area, while the dam also serves as a critical flood control measure. As climate change continues to impact water resources, the maintenance and upkeep of structures like Roundup Lake Dam are essential to protect both people and the environment.
As a key feature in the Buffalo District, Roundup Lake Dam showcases the intersection of human engineering with natural water systems. The dam's location in the city of Silo provides a valuable recreational resource for the community, offering opportunities for boating, fishing, and other outdoor activities. With its historical significance dating back over seven decades, Roundup Lake Dam represents a blend of functionality, safety, and enjoyment in the midst of Ohio's water landscape.

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 Roundup Lake Dam
Where does the data for Roundup 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 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.
