Glencliff Road Detention Basin Dam dam
Glencliff Road Detention Basin Dam
Located in Manlius, New York, the Glencliff Road Detention Basin Dam stands as a crucial structure for flood risk reduction along the TR-Sweet Road stream. Built in 1977, this earth dam stands at a height of 13 feet and spans a length of 148 feet, providing a storage capacity of 12 acre-feet. With a significant hazard potential, the dam has been assessed as satisfactory in condition, ensuring its effectiveness in mitigating potential flooding events in the region.
Managed by the local government and regulated by the New York State Department of Environmental Conservation, the dam is subject to regular inspections to ensure its structural integrity. In the event of an emergency, however, the absence of an Emergency Action Plan raises concerns about the preparedness for unforeseen events. Despite this, the dam continues to serve its primary purpose of reducing flood risks in the area, with a moderate risk assessment rating indicating a level of preparedness for potential hazards.
With a spillway width of 40 feet and a maximum discharge capacity of 907 cubic feet per second, the Glencliff Road Detention Basin Dam exemplifies the importance of proper infrastructure for water resource management and climate resilience. As climate change continues to impact precipitation patterns and increase the frequency of extreme weather events, structures like this play a vital role in protecting communities and infrastructure from the devastating effects of flooding.

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 Glencliff Road Detention Basin Dam
Where does the data for Glencliff Road Detention Basin 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.
