About this dam

Winnies Reef Dam

Winnies Reef Dam, located in Grangerville, Saratoga County, New York, is a concrete structure completed in 1979 primarily used for recreation along Fish Creek. With a height of 16 feet and a length of 180 feet, the dam boasts a storage capacity of 100,700 acre-feet and a surface area of 4,028 acres. Its spillway, which is controlled and 118 feet wide, ensures proper water management during times of high discharge.

Despite its significant hazard potential and poor condition assessment, Winnies Reef Dam remains a popular spot for water resource and climate enthusiasts in the area. Managed by private owners and regulated by the New York State Department of Environmental Conservation, the dam undergoes regular inspections to ensure its structural integrity and public safety. The dam's location within the New York District further highlights its importance in the region's water resource management.

As stakeholders continue to monitor and assess the risks associated with Winnies Reef Dam, its very high risk ranking underscores the need for comprehensive risk management measures to mitigate potential threats. With its rich history, picturesque surroundings, and vital role in recreational activities, Winnies Reef Dam stands as a key landmark for water enthusiasts and climate advocates alike in New York's Saratoga County.

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.

FAQ

About Winnies Reef Dam

Where does the data for Winnies Reef 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 Significant 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.
