Atwood Dam dam
Atwood Dam
Atwood Dam, also known as Atwood Lake, is a federal-owned structure located in New Cumberland, Ohio, along the Indian Fork of Conotton Creek. Completed in 1936, this earth dam stands at a height of 65 feet with a hydraulic height of 55 feet and a length of 3700 feet. Its primary purpose is flood risk reduction, while also serving as a fish and wildlife pond and recreation area. With a high hazard potential, the dam poses a risk of significant flooding downstream in cities such as New Philadelphia, New Comerstown, Coshocton, and Zanesville in the event of a breach.
US Army Corps of Engineers (USACE) is responsible for the management, maintenance, and oversight of Atwood Dam, conducting regular inspections and implementing risk management measures to ensure its safety and functionality. The dam is continuously monitored through a specialized instrumentation system, and emergency response actions are supported by conducting exercises and training with local and state emergency responders. Despite the identified risk of leak erosion along the left abutment, USACE is dedicated to improving the dam's robustness through an Interim Risk Reduction Measures Plan (IRRMP) to address specific concerns and ensure the safety and stability of Atwood Dam for the surrounding communities and infrastructure.

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 Atwood Dam
Where does the data for Atwood 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.
