Summary
Built in 1985, this earth dam stands at a height of 20 feet and has a length of 365 feet, providing a storage capacity of 9.5 acre-feet. While it has a fair condition assessment as of 2015, it is classified as having a significant hazard potential and a high risk level.
Managed by the NHDES Dam Bureau, the Milton Waste Water Lagoons Dam is regulated, permitted, inspected, and enforced by the state of New Hampshire. It falls under the jurisdiction of the state and undergoes regular inspections every four years. Despite being a buttress-type dam with no spillway, it plays a crucial role in water resource management in the Strafford County area. With its location in a high-risk area, the structure requires diligent risk management measures to ensure the safety of nearby communities and the surrounding environment.
For water resource and climate enthusiasts, the Milton Waste Water Lagoons Dam represents a vital piece of infrastructure that demands ongoing attention and maintenance. Its location in a populated area underscores the importance of effective risk assessment and management to prevent potential hazards and ensure the continued safe operation of this essential water management facility.

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.
