Eagle Harbor Waste Weir Dam dam
Eagle Harbor Waste Weir Dam
Located in Eagle Harbor, New York, the Eagle Harbor Waste Weir Dam stands as a testament to early 20th-century engineering, having been completed in 1918 for the primary purpose of navigation on the Otter Creek. This concrete dam, with a height of 18 feet and a length of 120 feet, has a storage capacity of 10,488 acre-feet and serves as a vital infrastructure for water management in the region. Despite its age, the dam remains state-regulated and is subject to regular inspections to ensure its structural integrity and functionality.
With a spillway width of 75 feet and a maximum discharge capacity of 905 cubic feet per second, the Eagle Harbor Waste Weir Dam presents a significant hazard potential that requires careful monitoring and management. Although its condition is currently rated as "Not Rated," the dam's risk assessment is considered moderate, highlighting the need for ongoing risk management measures. Given its historical significance and critical role in water resource management, the Eagle Harbor Waste Weir Dam serves as a key landmark for both water resource and climate enthusiasts interested in the intersection of infrastructure, environmental stewardship, and public safety in the face of changing climate 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 Eagle Harbor Waste Weir Dam
Where does the data for Eagle Harbor Waste Weir 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.
