Summary

The dam, completed in 1964, stands at a height of 12 feet with a hydraulic height of 10 feet, serving a primary purpose of water supply. It has a storage capacity of 150 acre-feet and a normal storage level of 120 acre-feet, covering a surface area of 111 acres.

The dam at North Auburn is classified as a concrete type with a length of 150 feet and a spillway width of 50 feet. It is regulated by the Maine Emergency Management Agency (MEMA), with state oversight for permitting, inspections, and enforcement. The dam is considered to have a significant hazard potential and has a scheduled inspection frequency of every 6 years, with the last assessment conducted in May 2020.

For water resource and climate enthusiasts, North Auburn offers an intriguing case study in dam infrastructure management and regulatory oversight. Its role in providing water supply to the region, combined with its design features and hazard potential, makes it a focal point for understanding the intersection of water resource management and climate resilience in the state of Maine.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
