Jennings Pond Dam dam
Jennings Pond Dam
Jennings Pond Dam, located in Danby, New York, is a state-owned structure that plays a vital role in water resource management and climate resilience. Built in 1986, this earth-type dam stands at a height of 17 feet and has a length of 565 feet, providing recreational opportunities for visitors in the area. With a storage capacity of 294 acre-feet and a surface area of 32 acres, the dam is situated on Buttermilk Creek and is regulated by the New York State Department of Environmental Conservation.
The dam's spillway, with a width of 20 feet, is classified as uncontrolled, and the structure is inspected every two years to ensure its safety and functionality. Despite being assessed as having a fair condition, the dam is designated as having a high hazard potential, highlighting the importance of regular monitoring and maintenance. In case of emergencies, the dam has an emergency action plan in place, although its last revision was in 2018. Overall, Jennings Pond Dam serves as a crucial infrastructure for both water management and recreational purposes in Tompkins County, New York.
As climate change continues to impact water resources and infrastructure, the maintenance and regulation of dams like Jennings Pond Dam become increasingly critical. With a moderate risk assessment rating, stakeholders and authorities must prioritize risk management measures to mitigate potential hazards and ensure the long-term sustainability of the dam. By staying proactive in monitoring and addressing any issues that may arise, Jennings Pond Dam can continue to fulfill its role in providing water storage, flood control, and recreational opportunities for the community while adapting to the changing climate conditions.

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 Jennings Pond Dam
Where does the data for Jennings 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 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.
