Summary
Completed in 1979, this private dam primarily serves a purpose other than water storage or flood control. Despite its modest size, the dam has a normal storage capacity of 0.21 acre-feet and a maximum storage of 0.4 acre-feet.
Managed and regulated by the New Hampshire Department of Environmental Services Dam Bureau, the Camp Foss Sewage Lagoon Dam poses a significant hazard potential due to its poor condition and high risk assessment rating. With no spillway and limited drainage area, the dam's structural integrity is a cause for concern. The last inspection in September 2019 revealed the need for frequent evaluations, indicating the ongoing attention required to ensure the community's safety.
For water resource and climate enthusiasts, understanding the complexities of maintaining and monitoring dams like Camp Foss Sewage Lagoon Dam is crucial for mitigating potential risks and safeguarding the surrounding environment. As climate change continues to impact water systems, the importance of proactive dam management becomes increasingly evident. The involvement of state regulatory agencies and regular inspections play a vital role in addressing the challenges posed by aging infrastructure to protect communities and water resources for future generations.

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.
