Hope Lake Dam dam
Hope Lake Dam
Hope Lake Dam, also known as Greek Peak Dam, is a local government-owned structure located in East Virgil, Cortland, New York. Completed in 1998, the dam serves primarily for recreational purposes, offering a picturesque setting for water resource and climate enthusiasts to enjoy. With a height of 30 feet and a length of 1132 feet, the dam holds a maximum storage capacity of 398 acre-feet and covers a surface area of 22 acres.
Managed by the New York State Department of Environmental Conservation (DEC), Hope Lake Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. The dam has an uncontrolled spillway type with a width of 252 feet, capable of discharging a maximum flow of 3007 cubic feet per second. The hazard potential of the dam is considered significant, with a moderate risk assessment score of 3, highlighting the importance of ongoing risk management measures and emergency preparedness.
Despite not being rated for its condition assessment, Hope Lake Dam remains a focal point for outdoor recreation and water-based activities in the region. With its tranquil surroundings and essential role in water resource management, the dam stands as a testament to the intersection of environmental stewardship and community engagement in safeguarding our natural resources for future generations.

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 Hope Lake Dam
Where does the data for Hope Lake 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.
