Summary

Built in 1910, this stone dam stands at a height of 16 feet and has a length of 128 feet, with a storage capacity of 460 acre-feet. The dam is situated on the Otter Creek and is regulated by the Federal Energy Regulatory Commission, making it a key player in the region's hydroelectric power generation.

With a low hazard potential and a moderate risk assessment rating, Proctor serves as a crucial infrastructure for water resource management in the area. Despite its age, the dam has been well-maintained and regularly inspected, with the last inspection taking place in August 2019. The dam's primary purpose of hydroelectric power generation highlights its significance in the region's energy production and sustainability efforts.

Proctor's unique design, historical significance, and role in renewable energy production make it a fascinating site for water resource and climate enthusiasts. As a public utility owned structure, this dam not only contributes to the local economy but also plays a vital role in water regulation and energy generation in Vermont's Rutland County. With its controlled spillway, storage capacity, and efficient operation, Proctor stands as a testament to the intersection of water resource management and sustainable energy production.

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.
