Summary

Built in 1895, this Earth-type dam stands at a height of 8 feet and stretches out for 760 feet, enclosing a storage capacity of 64 acre-feet. With a primary purpose of recreation, the reservoir offers a serene getaway for water resource and climate enthusiasts looking to explore the Pequabuck River Trib.

Despite its age, Farmington Reservoir Dam has a satisfactory condition assessment as of May 2019, with a high hazard potential due to its location. The dam is state-regulated and permitted, with regular inspections conducted to ensure its safety and functionality. The reservoir provides a maximum discharge of 525 cubic feet per second and has a spillway width of 32 feet, further showcasing its importance in managing water resources in the area.

Overall, Farmington Reservoir Dam serves as a significant landmark in Farmington, offering both recreational opportunities and essential water resource management functions. Its historical significance, coupled with its role in flood control and water supply, makes it a valuable asset in the region for both locals and visitors alike.

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.
