Summary
Built in 1973, this concrete structure stands at 13 feet high and spans a length of 70 feet, creating a reservoir with a storage capacity of 60 acre-feet. Situated on the Menunketesuck River, the dam plays a significant role in managing the water resources of the area, with a maximum discharge capacity of 275 cubic feet per second.
Despite being privately owned, Lockwood Lake Dam is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP), ensuring that it meets safety standards and undergoes regular inspections. The dam holds a significant hazard potential due to its location and size, but as of the most recent assessment in 2019, its condition was deemed satisfactory. While there are no associated structures or locks, the dam features a spillway with a width of 15 feet to manage overflow during high water events.
Enthusiasts of water resources and climate will appreciate the role that Lockwood Lake Dam plays in providing recreational opportunities while also serving as a crucial infrastructure for water management in the region. The dam's location on the Menunketesuck River and its design highlight the importance of sustainable dam operations and maintenance to ensure the safety of surrounding communities and the preservation of the local ecosystem. With its history dating back to the 1970s and ongoing regulatory oversight, Lockwood Lake Dam serves as a reminder of the vital intersection between human development and environmental stewardship in managing water resources effectively.

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.
