Conewango Creek Site 9a Dam dam
Conewango Creek Site 9a Dam
Conewango Creek Site 9a Dam, also known as Villenova Dam, is a local government-owned structure located in Wrights Corners, Chautauqua, New York. Built in 1972 by the USDA NRCS, this Earth-type dam stands at a height of 43 feet and spans 1590 feet along the TR-CONEWANGO CREEK. Its primary purpose is flood risk reduction, with a normal storage capacity of 41 acre-feet and a maximum storage of 964 acre-feet.
Managed by the NYS DEC, this dam has a hazard potential rated as high and a moderate risk assessment score of 3. Despite not being condition-rated, it undergoes inspections every two years, with the last one conducted in November 2020. The spillway width of 200 feet allows for a maximum discharge of 8200 cubic feet per second, ensuring effective flood control measures in the area.
With its crucial role in mitigating flood risks along Conewango Creek, Site 9a Dam serves as a vital infrastructure asset in safeguarding the surrounding community against potential water-related disasters. As water resource and climate enthusiasts, understanding the dynamics of this dam's design, purpose, and operational capacity sheds light on the importance of sustainable water management practices in maintaining a resilient environment.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Conewango Creek Site 9a Dam
Where does the data for Conewango 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.
