Summary

Completed in 1953, this earth dam stands at a height of 21 feet and spans a length of 600 feet, with a storage capacity of 79 acre-feet. Situated on the TR-East Branch Wappinger Creek, the dam plays a crucial role in managing water resources in the area.

The dam's spillway, with a width of 60 feet, is uncontrolled, allowing for the discharge of excess water during periods of high flow. Despite being classified as low hazard potential, the dam is subject to state regulations, inspections, and enforcement by the New York State Department of Environmental Conservation. The risk assessment for the dam is moderate, indicating a need for ongoing monitoring and management measures to ensure its continued safety and efficacy.

In addition to its irrigation function, R Corbetta Dam also serves recreational purposes, offering a surface area of 6 acres for activities such as fishing and boating. With its strategic location and vital role in water resource management, the dam stands as a key infrastructure asset in the region, contributing to both agricultural and recreational activities while ensuring the safety and security of surrounding communities.

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.
