Old Brodhead Lake Dam dam
Old Brodhead Lake Dam
Old Brodhead Lake Dam, located in Grahamsville, Sullivan, New York, is a privately owned structure with a primary purpose of serving as a Fish and Wildlife Pond. Completed in 2005, this earth dam stands at a height of 33 feet and spans a length of 1750 feet, providing a storage capacity of 547 acre-feet. The dam, situated on TR-Botsford Brook, plays a vital role in supporting recreational activities and maintaining the ecological balance of the area.
Managed by the NYS DEC, the dam is inspected regularly to ensure its structural integrity and operational efficiency. With a low hazard potential and a moderate risk assessment rating, the dam poses minimal threats to the surrounding community. Although the condition of the dam is currently not rated, it meets regulatory guidelines and is equipped with an Emergency Action Plan (EAP) to address any unforeseen events. Overall, Old Brodhead Lake Dam stands as a testament to responsible water resource management and conservation efforts in the region.
For water resource and climate enthusiasts, Old Brodhead Lake Dam offers a fascinating glimpse into the intersection of human infrastructure and environmental stewardship. Its role as a habitat for fish and wildlife, coupled with its recreational value, underscores the importance of striking a balance between development and conservation. As climate change continues to impact water resources, structures like Old Brodhead Lake Dam serve as crucial components in safeguarding ecosystems and supporting sustainable practices 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 Old Brodhead Lake Dam
Where does the data for Old Brodhead 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.
