Summary

Completed in 1913, this earth dam stands at a height of 8 feet and spans 200 feet in length. It serves a primary purpose of water supply, with a storage capacity of 36 acre-feet and a normal storage level of 24 acre-feet.

Managed by the NHDES Dam Bureau, the Dole Reservoir Dike is state-regulated, inspected, and enforced to ensure its safety and functionality. With a significant hazard potential but a satisfactory condition assessment as of October 2017, this structure plays a key role in managing water resources in the area. The dam has a moderate risk assessment level, indicating a need for ongoing monitoring and risk management measures to maintain its integrity and effectiveness.

For water resource and climate enthusiasts, the Dole Reservoir Dike offers a glimpse into the vital infrastructure that supports water supply in New Hampshire. With its historical significance and ongoing regulatory oversight, this dam serves as a critical component of the region's water management system, highlighting the importance of sustainable and resilient water resource infrastructure in the face of changing climate conditions.

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.
