Genegantslet Lake Dam dam
Genegantslet Lake Dam
Genegantslet Lake Dam, located in McDonough, New York, was completed in 1900 and serves as a recreational spot for water enthusiasts. The dam, primarily made of stone, stands at a height of 10 feet and stretches 300 feet in length across the Genegantslet Creek. With a storage capacity of 1064 acre-feet and a surface area of 112 acres, the dam provides a picturesque backdrop for outdoor activities.
Despite its scenic beauty, Genegantslet Lake Dam poses a high hazard potential due to its poor condition assessment as of June 2017. The dam's spillway, an uncontrolled type with a width of 300 feet, has a maximum discharge capacity of 5450 cubic feet per second. Although the dam is state-regulated and inspected regularly by the NYS DEC, the risk assessment remains at a moderate level (3), prompting the need for ongoing risk management measures.
Efforts to ensure the safety of Genegantslet Lake Dam include a biennial inspection frequency and the establishment of emergency action plans. While the dam's risk level is deemed moderate, its condition assessment and hazard potential underscore the importance of proactive maintenance and monitoring. As a vital water resource in Chenango County, Genegantslet Lake Dam serves as a reminder of the delicate balance between recreation and environmental 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 Genegantslet Lake Dam
Where does the data for Genegantslet 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 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.
