Southington Reservoir #1 Dam dam
Southington Reservoir #1 Dam
Southington Reservoir #1 Dam, located in Southington, Connecticut, serves as a crucial water supply infrastructure managed by the local government. 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
- 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.
- 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.
- 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.
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, environmental 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.

About Southington Reservoir #1 Dam
Where does the data for Southington Reservoir #1 Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
