Summary
Owned by the local government and regulated by the Department of Conservation and Recreation, this earth dam stands at a height of 11.5 feet and was completed in 1970. With a storage capacity of 178 acre-feet and a drainage area of 3.3 square miles, the culvert and tide gate help control water levels and protect the surrounding area from flooding.
Despite being classified as having a low hazard potential and fair condition assessment, the Mill River Culvert and Tide Gate still poses a moderate risk, according to the data. The last inspection in December 2010 revealed that the structure meets regulatory standards but may require regular monitoring and maintenance to ensure its continued reliability. With the potential for increased risks due to climate change and extreme weather events, it is essential for regulatory agencies and local authorities to implement risk management measures and emergency preparedness plans for this critical water resource infrastructure.
As water resource and climate enthusiasts, understanding the importance of structures like the Mill River Culvert and Tide Gate is crucial for preserving the integrity of our water systems and mitigating the impacts of climate change. By staying informed about the condition and management of such structures, we can work towards sustainable water management practices that ensure the long-term resilience of our communities in the face of a changing climate.

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.
