Carry Falls Dike D dam
Carry Falls Dike D
Carry Falls Dike D is a private-owned earth dam located in St. Lawrence, New York, along the Raquette River. Completed in 1953 for hydroelectric purposes, this dam stands at 28 feet in height and spans 400 feet in length, with a storage capacity of 104,463 acre-feet. Despite its significant contribution to hydroelectric power generation, the dam poses a high hazard potential due to its age and condition, although specific assessment data is not currently available.
Managed by the Federal Energy Regulatory Commission, Carry Falls Dike D has undergone regular inspections to ensure its structural integrity. It is part of a system of five associated structures, with no outlet gates or spillways, and is situated within a drainage area of 877 square miles. The dam's location in a high-risk zone underscores the importance of effective risk management measures and emergency preparedness plans to mitigate potential hazards and protect surrounding communities.
As a focal point for water resource and climate enthusiasts, Carry Falls Dike D exemplifies the critical balance between harnessing renewable energy sources and safeguarding environmental and public safety. Its historical significance, engineering design, and operational challenges make it a compelling case study for sustainable water resource management practices and the evolving role of dams in a changing climate.

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 Carry Falls Dike D
Where does the data for Carry Falls Dike D 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.
