Summary

Constructed in 1972, this Earth dam stands at a height of 25 feet and spans a length of 1600 feet, providing a storage capacity of 96 acre-feet. With a primary purpose of water supply, it serves the local community and helps manage water resources in the region.

Managed by the local government and regulated by the NYS DEC, Southeast Reservoir Dam is deemed to have a significant hazard potential. While its condition assessment is currently not rated, regular inspections are conducted every four years to ensure its structural integrity and safety. The dam's spillway type is listed as Uncontrolled, and it has a moderate risk assessment rating of 3, indicating the need for continued monitoring and risk management measures.

For water resource and climate enthusiasts, Southeast Reservoir Dam presents an intriguing case study in dam infrastructure management and water supply operations. As a critical component of the local water system in Monroe County, this dam serves as a cornerstone for sustainable water resource management in the region. With its historical significance and ongoing regulatory oversight, Southeast Reservoir Dam highlights the importance of maintaining and monitoring essential infrastructure to safeguard water resources for generations to come.

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.
