Harrisburg Lake Dam dam
Harrisburg Lake Dam
Harrisburg Lake Dam, located in Hope Falls, New York, was completed in 1918 and serves as a recreational site for enthusiasts of water resources and climate. With a dam height of 10 feet and a length of 210 feet, the dam boasts a storage capacity of 487 acre-feet and a surface area of 77 acres. The dam is primarily used for recreation purposes, providing a serene and scenic environment for visitors to enjoy.
Managed by the New York State Department of Environmental Conservation (NYS DEC), Harrisburg Lake Dam is regulated, inspected, and enforced to ensure its safety and functionality. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its moderate risk assessment rating, the dam has not been modified in recent years and meets regulatory guidelines, making it a stable and reliable structure for the surrounding community.
With an uncontrolled spillway type and a maximum discharge of 510 cubic feet per second, Harrisburg Lake Dam is equipped to handle moderate risks with a careful balance of safety and recreational enjoyment. As a beloved feature in the Warren County landscape, the dam serves as a testament to responsible water resource management and climate-conscious infrastructure development.

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 Harrisburg Lake Dam
Where does the data for Harrisburg 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 Low 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.
