Guilford Lake Dam dam
Guilford Lake Dam
Guilford Lake Dam, located in Guilford, New York, was completed in 1827 and serves as a crucial water supply source. The dam, standing at a height of 15 feet and with a length of 62 feet, holds a maximum storage capacity of 560 acre-feet and normal storage of 390 acre-feet. It regulates the flow of Guilford Creek and has a spillway width of 44 feet, capable of handling a maximum discharge of 1500 cubic feet per second.
Despite its historical significance and primary purpose of water supply, Guilford Lake Dam is categorized with a high hazard potential and poor condition assessment. The last inspection in May 2019 highlighted the need for improvements and maintenance. The dam poses a moderate risk level, prompting the consideration of risk management measures to ensure the safety and integrity of the structure and surrounding areas.
As water resource and climate enthusiasts, the data on Guilford Lake Dam serves as a reminder of the importance of monitoring and maintaining critical infrastructure for water management. The dam's role in regulating water flow and storage underscores its significance in the local ecosystem and community. Efforts to address the dam's condition and implement risk management strategies are essential to safeguarding water resources and mitigating potential hazards in the region.

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 Guilford Lake Dam
Where does the data for Guilford 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.
