Lake P'Na Dam dam
Lake P'Na Dam
Lake P'Na Dam, located in Columbiana, Ohio, is a private earth dam constructed in 1948 primarily for recreational purposes. With a height of 17 feet and a storage capacity of 139 acre-feet, the dam offers a surface area of 23.3 acres for various water-related activities. Managed by the Department of Natural Resources, the dam is regulated and inspected regularly to ensure its structural integrity and safety.
Despite its significant hazard potential and poor condition assessment, Lake P'Na Dam continues to attract water resource and climate enthusiasts seeking opportunities for outdoor recreation. The dam is situated in a tranquil setting, providing visitors with a peaceful retreat for fishing, boating, and other leisure activities. Its close proximity to the Mahoning River tributary makes it an ideal spot for observing the interconnectedness of water resources in the region.
As one of the key structures in the Pittsburgh District, Lake P'Na Dam serves as a vital component of the local water infrastructure. While facing challenges related to its condition and risk assessment, efforts are being made to ensure that the dam meets safety guidelines and emergency preparedness protocols. For water resource and climate enthusiasts, Lake P'Na Dam presents a unique opportunity to appreciate the beauty of nature while learning about the importance of responsible dam management in preserving valuable water resources.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Lake P'Na Dam
Where does the data for Lake P'Na 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.
