Summary
This dam has a height of 7 feet and a length of 4600 feet, with a storage capacity of 2200 acre-feet. The dam, situated along TR-SHAVER CREEK, is regulated and permitted by the NYS DEC, with state inspections and enforcement measures in place to ensure its safety and functionality.
Despite being classified as low hazard potential, the dam at Swamp Road Dike is considered to have a moderate risk level (3) and is currently assessed as "Not Rated" for its condition. Although it does not have an Emergency Action Plan (EAP) in place, the overall risk management measures for the dam have not been specified. With a spillway width of 52 feet and uncontrolled spillway type, the dam poses a moderate risk in the event of heavy rainfall or flooding. The risk assessment for this structure indicates a need for further evaluation and potentially enhanced risk mitigation strategies.
For water resource and climate enthusiasts, Swamp Road Dike presents an intriguing case study of a privately owned dam in New York with a focus on fish and wildlife conservation. The data surrounding its construction, storage capacity, and regulatory oversight by the NYS DEC offer insight into the complexities of managing such structures for both ecological and public safety purposes. As discussions around dam safety and risk management continue to evolve, the unique characteristics of Swamp Road Dike provide valuable insights into the challenges and considerations involved in maintaining and regulating water infrastructure 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.
