Summary

Managed by the local government, this Earth-type dam was completed in 1983 by designer James P. Olson. With a height of 35 feet and a capacity of 1567 acre-feet, Warren Lake serves primarily for recreational purposes and covers a surface area of 48 acres.

Despite its fair condition assessment and high hazard potential, Warren Lake remains a popular destination for outdoor enthusiasts and climate advocates. Set against the backdrop of Mills Brook, this dam plays a crucial role in the local ecosystem while providing opportunities for water-based activities. The dam's structure, consisting of stone core and soil foundations, reflects a harmonious blend of engineering and natural elements that contribute to its aesthetic appeal.

Warren Lake's location within the New England District adds to its significance as a water resource, attracting visitors from near and far to appreciate its beauty and recreational offerings. With state-regulated oversight from Vermont's Department of Environmental Conservation, the dam ensures safe and sustainable water management practices in an ever-changing climate landscape. As climate enthusiasts continue to advocate for responsible stewardship of water resources, Warren Lake stands as a shining example of the delicate balance between human intervention and environmental preservation.

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.
