Summary
The dam, constructed with an earth core and buttress type, stands at a height of 9 feet and has a hydraulic height of 5 feet. With a length of 332 feet, it impounds Fort Pond Brook and provides a storage capacity of 300 acre-feet.
Despite being classified as having a significant hazard potential, Warners Pond Dam is in satisfactory condition as of the last assessment in December 2012. It is regulated by the Department of Conservation and Recreation in Massachusetts, with state permitting, inspection, and enforcement procedures in place. The dam's spillway type is uncontrolled, with a surface area of 45 acres and a drainage area of 46.6 square miles.
With its picturesque location and recreational value, Warners Pond Dam is a vital asset in the Middlesex County area. Although it poses a moderate risk, the dam's condition and management measures ensure its safety and functionality for water resource and climate enthusiasts to enjoy for years to come.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
