About this dam

Wolf Run Lake Dam

Wolf Run Lake Dam, located in Noble, Ohio, is a vital structure designed by the USDA NRCS to reduce flood risks along the Wolf Run stream. Completed in 1966, this earth dam stands at a height of 76 feet and spans 700 feet, providing crucial flood protection for the surrounding area. With a normal storage capacity of 4137 acre-feet and a maximum discharge of 19948 cubic feet per second, the dam plays a crucial role in managing water resources in the region.

Managed by the Ohio Department of Natural Resources, Wolf Run Lake Dam is subject to state regulations, inspections, and enforcement to ensure its structural integrity and public safety. Despite being classified as having a high hazard potential, the dam's condition assessment indicates it is currently in fair condition. Its risk assessment is moderate, signaling the need for ongoing monitoring and management measures to address any potential risks. With a capacity of 7737 acre-feet and a surface area of 214 acres, the dam serves as a key infrastructure for water resource management and flood protection in the area.

In the event of an emergency, the dam's Emergency Action Plan (EAP) is prepared to meet guidelines and ensure the safety of nearby residents. With Bill Johnson (R) as the congressional representative for the area, the Wolf Run Lake Dam stands as a critical piece of infrastructure that underscores the importance of effective water resource and climate management in mitigating flood risks and safeguarding communities.

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 Wolf Run Lake Dam

Where does the data for Wolf Run 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.
