Lapp Pond Dam dam
Lapp Pond Dam
Lapp Pond Dam, also known as the Chesnut Ridge Rod & Gun Club, is a private dam located in South Dover, New York. Built in 1932, this masonry dam stands at a height of 6.5 feet and spans 325 feet in length, creating a surface area of 36 acres. Situated on Cooperstown Brook, the dam serves primarily for recreational purposes and is regulated by the New York State Department of Environmental Conservation.
With a significant hazard potential and a moderate risk assessment rating, Lapp Pond Dam undergoes inspections every four years to ensure its safety and structural integrity. Despite being uncontrolled, the dam boasts a spillway width of 16 feet to manage water flow. The surrounding area of Dutchess County, New York, benefits from the recreational opportunities provided by the dam, attracting water resource and climate enthusiasts to appreciate its contribution to the local ecosystem.
As one of the essential structures in the region, Lapp Pond Dam plays a crucial role in water management and environmental preservation. Its historical significance, combined with its recreational value, highlights the importance of maintaining and monitoring dams like this to safeguard the surrounding communities and natural habitats. For water resource and climate enthusiasts, Lapp Pond Dam stands as a testament to human ingenuity in balancing infrastructure development with environmental stewardship.
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.

About Lapp Pond Dam
Where does the data for Lapp 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 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.
