Williams Pond Dam dam
Williams Pond Dam
Williams Pond Dam, also known as Williams Pond Soap Factory Pond, is a private-owned structure located in Glastonbury, Connecticut. Built in 1900, this concrete dam stands at a height of 17 feet and spans 190 feet in length, creating a reservoir with a storage capacity of 25 acre-feet. The dam's primary purpose is for recreation, offering a serene spot for water enthusiasts to enjoy.
Despite its recreational appeal, Williams Pond Dam poses a high hazard potential and has been rated in poor condition as of the last assessment in 2014. The dam is state-regulated and subject to regular inspections, but its maintenance and safety measures may be lacking. With a drainage area of 2.2 square miles and a spillway width of 8 feet, the dam's capacity to handle maximum discharge of 212 cubic feet per second is crucial for flood protection in the area.
Given its age and condition, Williams Pond Dam warrants careful monitoring and potentially updated risk assessment and management measures to ensure the safety of downstream communities and the preservation of the surrounding environment. Water resource and climate enthusiasts interested in the intersection of infrastructure and natural resources would find this dam a compelling case study for understanding the challenges of maintaining aging structures in the face of evolving climate conditions.

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 Williams Pond Dam
Where does the data for Williams 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 High 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.
