About this dam

Willowdale Lake Dam

Located in Stark County, Ohio, the Willowdale Lake Dam stands as a testament to engineering excellence, having been completed in 1924 by the prestigious AMBURSEN ENGINEERING CORPORATION from New York. With a primary purpose of recreation, this earth dam stretches 350 feet in length and rises to a height of 27.3 feet, providing storage of up to 563 acre-feet of water. Nestled along the picturesque Nimisila Creek, this dam offers a surface area of 48.5 acres and a drainage area of 6.06 square miles, making it a vital resource for the surrounding community of Comet.

Regulated by the Ohio Department of Natural Resources, the Willowdale Lake Dam is subject to regular inspections to ensure its structural integrity and safety. With a significant hazard potential yet a satisfactory condition assessment as of June 2015, this dam plays a crucial role in flood control and water management in the region. Despite its age, the dam continues to serve its purpose effectively, attracting water resource and climate enthusiasts alike to appreciate its historical significance and contribution to the local ecosystem.

As a symbol of resilience and ingenuity, the Willowdale Lake Dam stands as a beacon of environmental stewardship and sustainable water resource management. With its rich history and vital role in the community, this dam is not just a structure but a testament to human innovation in harnessing the power of nature for the benefit of all. Whether for recreation or flood control, this earth dam continues to be a cornerstone of the region's water infrastructure, embodying the harmonious relationship between humans and the environment.

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 Willowdale Lake Dam

Where does the data for Willowdale 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.
