Summary
Built in 1811, this earth dam with a buttress core spans 125 feet in length and reaches a height of 7.5 feet, offering a storage capacity of 100 acre-feet. The dam regulates Clark Pond Brook, covering a surface area of 40 acres and draining a 14.5-square-mile watershed.
State-regulated by the NHDES Dam Bureau, this dam is subject to regular inspections and enforcement to ensure its structural integrity and the safety of surrounding communities. While categorized with a low hazard potential, the dam's condition assessment is rated as fair, and a moderate risk assessment (3) has been identified. Despite these challenges, Clark Pond East Dam remains a vital asset for water supply in the region, highlighting the importance of proactive risk management and emergency preparedness for sustainable water resource utilization.
As a cornerstone of local government infrastructure, Clark Pond East Dam serves as a critical component in the water supply network of Rockingham County. With a history dating back over two centuries, this dam symbolizes the ongoing efforts to balance water resource management and climate resilience. As enthusiasts in these fields continue to monitor and assess the dam's condition, collaborative efforts with regulatory agencies and stakeholders are essential to ensure the long-term sustainability and safety of this essential water infrastructure.

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.
