Popes Pond Dam Dam
Popes Pond Dam
Popes Pond Dam, also known as Popes Pond Streets Pond, is a vital water resource infrastructure located in Wilton, Connecticut. Built in 1965 for water supply purposes, this earth dam stands at a height of 24 feet with a length of 650 feet and a storage capacity of 1460 acre-feet. Situated on Barretts Brook, it serves as a key component in the management of Fairfield County's water resources, with a normal storage capacity of 980 acre-feet and a surface area of 87.5 acres.
Managed by the Connecticut Department of Energy and Environmental Protection, Popes Pond Dam is subject to regular inspections and enforcement measures to ensure its structural integrity and operational efficiency. With a high hazard potential but a satisfactory condition assessment as of May 2019, this dam plays a crucial role in flood control and water supply management in the region. Despite its moderate risk assessment rating of 3, proper risk management measures are in place to address any potential issues that may arise.
In the event of an emergency, Popes Pond Dam is equipped with an Emergency Action Plan (EAP) to guide response efforts. With a spillway width of 200 feet and a maximum discharge capacity of 7600 cubic feet per second, the dam is designed to handle significant inflows during flood events. Overall, Popes Pond Dam stands as a testament to the importance of sustainable water resource management and climate resilience in the face of changing environmental conditions.

About Popes Pond Dam
Where does the data for Popes 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 below 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.

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.
