Pomeroy Pond No. 1 Dam dam
Pomeroy Pond No. 1 Dam
Pomeroy Pond No. 1 Dam, also known as Pomeroy Dam, is a privately owned structure located in Cheshire, Ohio. Built in 1965 by USDA NRCS, this earth dam serves the primary purpose of recreation and is regulated by the Department of Natural Resources in the state of Ohio. The dam stands at a height of 28.6 feet and has a length of 190 feet, with a storage capacity of 81.4 acre-feet and a surface area of 4.5 acres. It is situated on a tributary to Alum Creek in Delaware County, Ohio.
Despite its low hazard potential and fair condition assessment, the dam has a moderate risk rating of 3 according to the data. The spillway is uncontrolled, and the outlet gates are also uncontrolled. The last inspection was conducted in December 2020, with a scheduled inspection frequency of 5 years. The dam is designed to handle a maximum discharge of 255 cubic feet per second, with a drainage area of 0.34 square miles.
Overall, Pomeroy Pond No. 1 Dam represents an important recreational resource in the area, providing opportunities for water-based activities and enjoyment. Its historic construction by USDA NRCS and ongoing regulation by the state of Ohio ensure its safety and functionality for both visitors and the surrounding environment. For water resource and climate enthusiasts, this dam serves as a fascinating example of sustainable infrastructure development and management in the region.

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 Pomeroy Pond No. 1 Dam
Where does the data for Pomeroy Pond No. 1 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 Low 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.
