Pond Lily Dam dam
Pond Lily Dam
Pond Lily Dam, located in Snyderville, New York, is a privately owned structure regulated by the NYS DEC. The dam, primarily used for recreation, is an Earth type with a height of 9 feet and a length of 225 feet. It holds a storage capacity of 130 acre-feet with a normal storage of 104 acre-feet, covering a surface area of 26 acres and draining a small area of 0.19 square miles in the Doove Kill river.
Despite being categorized as having a low hazard potential, the dam's risk assessment is moderate. The last inspection conducted was in June 1998, with no recent condition assessment available. The spillway type is uncontrolled with a width of 10 feet, and the dam has not been modified in recent years. While emergency action plans, inundation maps, and risk management measures are not currently documented, the dam remains a focal point of interest for water resource and climate enthusiasts due to its unique design and location.
In the midst of changing climate patterns and increasing concerns about water resource management, the Pond Lily Dam serves as a reminder of the importance of maintaining and monitoring dam infrastructure. With its recreational purpose and historical significance in the region, efforts to enhance its safety and resilience are essential for both the community and the environment. As discussions on water conservation and climate adaptation continue to evolve, the Pond Lily Dam stands as a tangible example of the intersection between human activity and natural resources.

About Pond Lily Dam
Where does the data for Pond Lily 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 below 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.

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.
