Doubletree Subdivision Dam dam
Doubletree Subdivision Dam
Doubletree Subdivision Dam, located in Jamesville, New York, was completed in 1991 with the primary purpose of flood risk reduction. This earthen dam stands at 28 feet in height and spans 450 feet in length, with a storage capacity of 4 acre-feet. Despite its significant hazard potential, the dam's condition assessment is rated as poor, highlighting the need for ongoing maintenance and monitoring.
Managed by the local government and regulated by the New York State Department of Environmental Conservation, Doubletree Subdivision Dam is subject to regular inspections to ensure its structural integrity and compliance with safety standards. The dam features an uncontrolled spillway type with a width of 4 feet, capable of discharging a maximum of 215 cubic feet per second. While the risk assessment for the dam is moderate, with a rating of 3 out of 5, there is a need for improved risk management measures and maintenance to mitigate potential hazards.
Water resource and climate enthusiasts interested in the management and maintenance of dams will find Doubletree Subdivision Dam a compelling case study. With its location in Onondaga County and its critical role in flood risk reduction, this dam serves as a focal point for understanding the complexities of dam infrastructure, regulatory oversight, and risk management in the face of changing environmental conditions.

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 Doubletree Subdivision Dam
Where does the data for Doubletree Subdivision 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.
