Summary

Completed in 1936, this earth dam stands at 18 feet tall and spans 500 feet in length, with a storage capacity of 698 acre-feet. The dam plays a crucial role in managing water resources in the region, with a normal storage level of 652 acre-feet and a surface area of 29 acres.

Despite its age, the dam is deemed to be in satisfactory condition as of the last assessment in June 2018. However, due to its high hazard potential, regular inspections are conducted, with the most recent one taking place in August 2020. The dam is regulated by the New York State Department of Environmental Conservation, and various state agencies are involved in permitting, inspection, and enforcement to ensure its safety and compliance with regulations.

With its strategic location and key role in water supply management, Loudonville Reservoir Dam stands as a significant infrastructure asset in the region. Climate and water resource enthusiasts will find interest in the dam's design, purpose, and the measures in place to mitigate potential risks, making it a notable site for further study and appreciation of water resource management practices.

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.
