Nanticoke Creek Site 9a Dam dam
Nanticoke Creek Site 9a Dam
Located in Nanticoke, Broome County, New York, the Nanticoke Creek Site 9a Dam stands as a vital structure for flood risk reduction along the Nanticoke Creek. Built in 1965 by the USDA NRCS, this earth dam reaches a height of 37 feet and spans 355 feet in length. With a storage capacity of 480 acre-feet and a maximum discharge of 2445 cubic feet per second, the dam plays a crucial role in protecting the surrounding area from potential flooding events.
Regulated by the NYS DEC and subject to state permitting, inspection, and enforcement, the Nanticoke Creek Site 9a Dam is classified as having a high hazard potential but remains in satisfactory condition as of the last assessment in October 2019. Despite its importance for flood risk reduction, the dam poses a moderate risk level (3) according to the risk assessment. With a spillway width of 150 feet and an uncontrolled spillway type, the dam's emergency action plan status, inundation maps, and risk management measures remain unspecified, highlighting areas for further improvement in emergency preparedness and response.
With its location in an area prone to flooding and its role in safeguarding the community, the Nanticoke Creek Site 9a Dam represents a critical piece of infrastructure in ensuring water resource management and climate resilience. As efforts continue to monitor and maintain the dam's condition, stakeholders and enthusiasts in water resources and climate are reminded of the ongoing importance of proactive risk management and emergency preparedness in mitigating potential hazards and protecting the surrounding environment and residents.

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 Nanticoke Creek Site 9a Dam
Where does the data for Nanticoke Creek Site 9a 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.
