Mount Airy dam
Mount Airy
Mount Airy, located in Monroe, Pennsylvania, is a privately-owned recreational dam constructed in 1974 on the Forest Hills Run river. The earth dam stands at a height of 42 feet and stretches 700 feet in length, providing storage for 284 acre-feet of water with a normal storage capacity of 187 acre-feet. Despite its impressive size, Mount Airy has a poor condition assessment and a high hazard potential, highlighting the need for regular inspections and maintenance to ensure public safety.
Managed by the Pennsylvania Department of Environmental Protection, Mount Airy is subject to state regulations and inspections to uphold safety standards. The dam is situated in Paradise Township and is used primarily for recreational purposes, offering a surface area of 16 acres for outdoor activities. With a location that attracts water resource and climate enthusiasts, Mount Airy's significance lies not only in its recreational value but also in its essential role in water storage and management within the region.
Although Mount Airy poses potential risks due to its condition and hazard level, its association with the Philadelphia District of the US Army Corps of Engineers indicates a commitment to risk management and safety measures. With a focus on maintaining the dam's integrity and ensuring emergency preparedness, Mount Airy serves as a vital structure for both recreation and water resource management in the area, drawing attention from those interested in sustainable water practices and climate resilience.

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 Mount Airy
Where does the data for Mount Airy 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.
