Tamarack Swamp Dam Dam
Tamarack Swamp Dam
Tamarack Swamp Dam, also known as F H Bontecou Pond, is a privately owned structure located in Stanfordville, New York. Completed in 1959, this earth dam serves primarily for flood risk reduction along the TR-WAPPINGER CREEK, within Dutchess County. With a height of 14 feet and a length of 1130 feet, the dam has a storage capacity of 710 acre-feet and a surface area of 133 acres.
Although the dam is classified as having a low hazard potential, it is considered to have a high risk level due to its condition being "Not Rated." The New York State Department of Environmental Conservation regulates the dam, ensuring it meets state permitting, inspection, and enforcement requirements. The primary purpose of Tamarack Swamp Dam is flood risk reduction, but it also serves purposes such as fire protection, irrigation, and creating a small fish pond.
Despite not having a spillway, the dam has a spillway width of 65 feet and a maximum discharge capacity of 1560 cubic feet per second. As of the last inspection conducted in March 2010, the dam's condition assessment is "Not Rated," indicating a need for further evaluation and maintenance to ensure its continued effectiveness in flood risk reduction and other purposes.

About Tamarack Swamp Dam
Where does the data for Tamarack Swamp 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 below 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.

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.
