Summary
Built in 1920, this earth dam stands at a height of 10 feet and has a hydraulic height of 6 feet. With a storage capacity of 200 acre-feet and a normal storage of 130 acre-feet, this dam serves the primary purpose of water supply for the surrounding area.
Despite its historical significance, the Lower Artichoke Reservoir Dam is facing challenges with a poor condition assessment as of 2009. With a low hazard potential but moderate risk assessment, there is a need for improved risk management measures to ensure the safety and sustainability of this vital water resource infrastructure. As a regulated structure under Massachusetts jurisdiction, ongoing inspections and enforcement are essential to address the dam's maintenance needs and prevent potential hazards.
For water resource and climate enthusiasts, the Lower Artichoke Reservoir Dam presents an opportunity to explore the intersection of infrastructure management, environmental conservation, and community water supply. With a rich history dating back to the early 20th century, this dam serves as a reminder of the importance of proactive maintenance and risk assessment in ensuring the resilience of our water systems in the face of changing climate conditions. As efforts to address the dam's poor condition continue, there is a chance for stakeholders to come together in safeguarding this valuable resource for future generations.

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.
