Spillway E-2 Bypass Dam dam
Spillway E-2 Bypass Dam
Spillway E-2 Bypass Dam, located in the Village of Waterford, Saratoga County, New York, serves as a crucial structure for navigation along the Erie Canal. Completed in 1918, this earthen dam stands at a height of 15 feet and spans 141 feet in length, with a maximum storage capacity of 118 acre-feet. Despite its age, the dam is in satisfactory condition and is regulated, permitted, inspected, and enforced by the New York State Department of Environmental Conservation.
With a high hazard potential due to its location and function, the Spillway E-2 Bypass Dam is subject to regular inspections every two years to ensure its structural integrity and safety. The dam's emergency action plan status and risk assessment are currently moderate, indicating a need for continued monitoring and risk management measures to mitigate potential threats. The dam's spillway type is uncontrolled, with a maximum discharge capacity of 1260 cubic feet per second, making it a critical component of the region's water resource infrastructure.
Water resource and climate enthusiasts will find the Spillway E-2 Bypass Dam a fascinating example of early 20th-century engineering designed to facilitate navigation and water management along the Erie Canal. Its historical significance, combined with its vital role in modern-day water infrastructure, highlights the importance of maintaining and monitoring aging dams to ensure the safety and sustainability of our water resources 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 Spillway E-2 Bypass Dam
Where does the data for Spillway E-2 Bypass 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 High 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.
