Killingly Pond Dam dam
Killingly Pond Dam
Killingly Pond Dam, located in Killingly, Connecticut, serves as a crucial structure regulating the flow of Whetstone Brook. Built in 1900, this masonry dam stands at a height of 15 feet and spans a length of 274 feet, with a storage capacity of 715 acre-feet. The dam is classified as having a "Significant" hazard potential and is deemed to be in "Fair" condition based on a 2019 assessment.
With a maximum discharge capacity of 30 cubic feet per second, Killingly Pond Dam plays a vital role in managing water resources and mitigating flood risks in the region. The dam is under state jurisdiction and regulation, with inspections conducted every five years to ensure its structural integrity and functionality. Despite its age, the dam continues to operate effectively, showcasing its importance in safeguarding the surrounding community and environment.
As a key component of the local water infrastructure, Killingly Pond Dam stands as a testament to the engineering feats of the past while serving as a reminder of the ongoing need for sustainable water resource management in the face of climate change. The dam's very high risk assessment rating underscores the critical role it plays in protecting lives and property from potential flooding events. As water resource and climate enthusiasts, understanding and supporting structures like Killingly Pond Dam is essential in ensuring the resilience of our communities in the face of evolving environmental challenges.

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 Killingly Pond Dam
Where does the data for Killingly Pond 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.
