Masonville Dam dam
Masonville Dam
Located in East Masonville, New York, the Masonville Dam is a private-owned structure that is regulated by the New York State Department of Environmental Conservation. The dam, built on East Masonville Creek, stands at a height of 30 feet and has a length of 65 feet, providing recreational opportunities for visitors in the area. With a storage capacity of 230 acre-feet and a surface area of 21 acres, the dam serves primarily for recreational purposes.
Despite being rated as having a low hazard potential, the Masonville Dam has a high risk assessment due to its outdated inspection records dating back to December 1996. The dam's condition is currently not rated, and there is no Emergency Action Plan prepared or updated for potential risks. While the dam meets guidelines for risk assessment, there is a need for further evaluation and management measures to ensure the safety and stability of the structure for both recreational users and the surrounding community.
With its picturesque location and recreational offerings, the Masonville Dam presents an opportunity for water resource and climate enthusiasts to explore the intersection of human-made structures and environmental conservation. As efforts continue to assess and manage the risks associated with the dam, there is a growing need for proactive measures to address any potential hazards and ensure the long-term sustainability of this important recreational resource in Delaware County, New York.
Dam data reference
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

About Masonville Dam
Where does the data for Masonville 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.
