De Flora Brothers Dam Lower dam
De Flora Brothers Dam Lower
De Flora Brothers Dam Lower, located in East Park, New York, is a private dam managed by the NYS DEC. Built in 1959, this earth dam stands at a height of 28 feet and spans 690 feet in length, providing recreational opportunities in the area. With a storage capacity of 430 acre-feet and a drainage area of 0.49 square miles, the dam poses a significant hazard potential and is classified as having a moderate risk level.
Despite not having a condition assessment rating, the dam has been inspected as recently as November 2020, with inspections occurring every four years. The spillway, with a width of 40 feet, is uncontrolled, allowing for a maximum discharge of 700 cubic feet per second. The dam's primary purpose is recreation, with a surface area of 43 acres and normal storage capacity of 326 acre-feet. While the dam is not owned or funded by federal agencies, it falls under state jurisdiction and regulation, ensuring its safety and compliance with inspection and enforcement measures.
Overall, De Flora Brothers Dam Lower serves as a vital recreational resource in Dutchess County, New York, offering opportunities for water enthusiasts to enjoy the tranquil surroundings of TR-CRUM ELBOW CREEK. With its significant hazard potential and moderate risk assessment, continued monitoring and maintenance of the dam are essential to ensure public safety and the preservation of this valuable water resource for future generations.
Dam data reference
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 De Flora Brothers Dam Lower
Where does the data for De Flora Brothers Dam Lower 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.
