Summary

Completed in 1955, this earthen dam stands at a height of 12 feet and spans 200 feet in length, creating a reservoir with a storage capacity of 1141.8 acre-feet. The dam is situated on the TR-Peekskill Hollow Creek and is regulated by the New York State Department of Environmental Conservation (NYS DEC).

With a hazard potential rated as "high" and a condition assessment deemed "satisfactory," Marcell Roth Lake Dam is subject to regular inspections, with the most recent conducted in November 2020. Despite its high-risk classification, the dam has not undergone modifications or enhancements in recent years. The dam's spillway, characterized as "controlled", has a width of 19 feet, enabling it to discharge a maximum of 155 cubic feet per second during peak flows. Additionally, the dam's location within a relatively small drainage area of 0.5 square miles underscores the importance of efficient water management practices to prevent potential inundation and associated risks.

In the realm of water resource and climate management, Marcell Roth Lake Dam serves as a focal point for both recreational activities and critical infrastructure maintenance. Its strategic location and regulatory oversight by state agencies underscore the importance of ensuring its structural integrity and emergency preparedness. As climate change impacts continue to pose challenges to water resource management, the resilience and risk management measures implemented at Marcell Roth Lake Dam will be essential in safeguarding surrounding communities and ecosystems from potential hazards.

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. 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

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, 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.
