East Br Cazenovia Creek Legion Dam dam
East Br Cazenovia Creek Legion Dam
East Br Cazenovia Creek Legion Dam, located in East Aurora, New York, is a rockfill dam completed in 1960 with a primary purpose of flood risk reduction along the East Branch of Cazenovia Creek. Standing at a height of 13 feet and a length of 165 feet, the dam provides a storage capacity of 118 acre-feet and covers a drainage area of 50.1 square miles. Despite its low hazard potential, the dam has a high risk assessment rating of 2, highlighting the importance of its role in managing flood risks in the region.
Managed by the local government and regulated by the New York State Department of Environmental Conservation, East Br Cazenovia Creek Legion Dam has not been rated for its condition assessment. The last inspection was conducted in July 2011, indicating a lack of recent evaluation. With a maximum discharge capacity of 5900 cubic feet per second and no spillway, the dam's performance in extreme weather events is crucial for protecting downstream communities. As a significant infrastructure for flood control, the dam plays a vital role in safeguarding the surrounding areas from potential water-related disasters.
While the dam is not owned or funded by federal agencies, its operation and maintenance are overseen by the local government, emphasizing the importance of community involvement in water resource management. With its strategic location and critical function in flood risk reduction, East Br Cazenovia Creek Legion Dam serves as a key asset in the region's water infrastructure, highlighting the intersection of water resource management and climate resilience in safeguarding communities against natural hazards.

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 East Br Cazenovia Creek Legion Dam
Where does the data for East Br Cazenovia Creek Legion 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.
