Summary
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.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
