Summary
The dam, primarily constructed of masonry, stands at a height of 18 feet and spans a length of 176.2 feet. It is situated on Humiston Brook and is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP), with state permitting, inspection, and enforcement in place to ensure its safety and functionality.
With a significant hazard potential but a satisfactory condition assessment as of August 2019, the dam is inspected every five years to maintain its integrity. The primary purpose of Southington Reservoir #1 Dam is to provide water supply, with a normal storage capacity of 0 acre-feet and a surface area of 1.45 acres. Despite not being federally owned or funded, the dam plays a vital role in safeguarding water resources in the region, highlighting the importance of local government involvement in water management and conservation efforts.
Supported by local regulatory agencies and with emergency action plans in place, Southington Reservoir #1 Dam stands as a crucial infrastructure for water resource management in Hartford County. As climate change impacts water availability and quality, ensuring the safety and functionality of dams like this becomes increasingly important for sustaining water security in the region. With ongoing monitoring and maintenance, Southington Reservoir #1 Dam continues to serve as a vital component of the local water supply infrastructure, contributing to resilience in the face of changing environmental conditions.

Dam Data Reference
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.
