Lilly Pond Dam dam
Lilly Pond Dam
Lilly Pond Dam, located in Parksville, New York, is a vital water supply structure owned by the local government. Built in 1922, this earth dam stands at 8 feet high and spans 185 feet in length, providing a storage capacity of 210 acre-feet. Situated on the TR-Little Beaver Kill river, the dam serves the primary purpose of water supply for the surrounding area.
Despite being classified with a low hazard potential, Lilly Pond Dam is considered to have a high risk level due to its age and lack of recent condition assessments. The dam has not been rated for its current condition, and the last inspection took place in October 2014. While the dam does not have a spillway, it meets the state regulatory requirements for permitting, inspection, and enforcement, ensuring compliance with safety standards and emergency preparedness.
Water resource and climate enthusiasts are drawn to Lilly Pond Dam for its historical significance, engineering design, and role in providing water supply to the region. With its unique location and connection to the TR-Little Beaver Kill river, this structure remains a key component of the local water infrastructure in Sullivan County, New York. As efforts continue to assess and manage the risks associated with the dam, its importance in maintaining water resources for the community is underscored.

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 Lilly Pond Dam
Where does the data for Lilly Pond 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.
