Summary

The earth dam, completed in 1890, stands at a height of 18 feet and has a structural height of 21 feet, spanning a length of 470 feet. The pond covers a surface area of 65 acres and is fed by the South Wheelock Branch-TR river or stream, serving as a vital resource for the community.

Managed by the local government and regulated by the Vermont Department of Environmental Conservation (DEC), Chandler Pond plays a crucial role in providing water for various purposes. The dam's condition is assessed as fair, with a hazard potential deemed significant. Regular inspections are conducted, with the most recent assessment taking place in August 2015, ensuring the safety and functionality of the structure.

For water resource and climate enthusiasts, Chandler Pond offers a fascinating example of historic dam infrastructure in Vermont. With its multi-arch core type and soil foundation, the pond stands as a testament to the importance of water management and conservation efforts in the region. As a state-regulated and inspected facility, Chandler Pond exemplifies the commitment to maintaining and safeguarding valuable water resources for future generations.

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.
