Vincent Manzo Dam & Dike dam
Vincent Manzo Dam & Dike
Vincent Manzo Dam & Dike, located in Garrattsville, New York, is a privately owned structure built in 1967 primarily for recreational purposes. Situated on the Butternut Creek, this earth dam stands at a height of 18 feet and stretches for 250 feet in length, with a storage capacity of 64 acre-feet. The dam's spillway, with a width of 52 feet, is uncontrolled, and the maximum discharge capacity is 235 cubic feet per second.
Although the hazard potential is classified as low, the risk assessment for the dam is moderate. The dam has not been rated for its condition, and the last inspection was conducted in July 1996. The regulatory oversight and enforcement of the dam fall under the purview of the New York State Department of Environmental Conservation. While the dam has not undergone any significant modifications over the years, it remains a key structure in the management of water resources in the area.
Despite its low hazard potential, the Vincent Manzo Dam & Dike plays a crucial role in the recreational activities and water resource management of the region. With its tranquil surroundings and strategic location, this dam serves as a vital infrastructure for the local community while also posing a moderate risk that requires ongoing monitoring and assessment to ensure its safety and functionality in the face of potential climate challenges.

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 Vincent Manzo Dam & Dike
Where does the data for Vincent Manzo Dam & Dike 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.
