Summary
Constructed in 1913, this earth dam stands at a height of 43 feet and spans 526 feet in length, with a storage capacity of 133 acre-feet. Situated on the TR Stevens Brook, the dam serves the surrounding area with a normal storage capacity of 123 acre-feet, covering a surface area of 9.2 acres and draining a 0.05 square mile watershed.
Maintained by the NHDES Dam Bureau, Dole Reservoir Dam has been deemed to have a high hazard potential but is currently in satisfactory condition, as assessed in October 2017. With a moderate risk rating, the dam undergoes inspections every two years, with the last inspection conducted in July 2019. The spillway type is uncontrolled with a width of 30 feet, capable of handling a maximum discharge of 160 cubic feet per second. Despite its age, the dam continues to meet regulatory standards, providing a crucial water resource for the region while managing potential risks effectively.
For water resource and climate enthusiasts, Dole Reservoir Dam presents a historic yet functional piece of infrastructure that plays a crucial role in ensuring water supply reliability in the area. With a focus on safety and regulatory compliance, the dam's management by the local government and oversight by the state regulatory agency highlight the importance of sustainable water resource management in the face of changing climate conditions. As a key component of the region's water infrastructure, the dam serves as a reminder of the ongoing efforts to balance water supply needs with environmental considerations and risk management strategies in the face of potential hazards.

Dam Data Reference
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.
