About this dam

Samuel Bargh Reservoir Dam

Located in Stamford, Connecticut, the Samuel Bargh Reservoir Dam stands as a vital piece of infrastructure for water resource management in the area. Completed in 1955, this earth dam spans 950 feet in length and reaches a height of 75 feet, with a storage capacity of 7,515 acre-feet. Situated on the Mianus River, the reservoir serves as a critical water supply for the region, ensuring a reliable source of water for the community.

Managed by the Department of Energy and Environmental Protection (DEEP) in Connecticut, the Samuel Bargh Reservoir Dam is subject to regular inspections and enforcement to maintain its high hazard potential. Despite this, the dam's condition is assessed as satisfactory, with a well-prepared Emergency Action Plan (EAP) in place. With a drainage area of 18.3 square miles and a maximum discharge capacity of 3,000 cubic feet per second, the dam plays a crucial role in flood control and water management efforts in the area.

As a significant structure in the New England District, the Samuel Bargh Reservoir Dam not only ensures water supply but also contributes to the overall ecosystem and climate resilience of the region. With its strategic location on the Mianus River and its capacity to store water effectively, this dam stands as a testament to sustainable water resource management and adaptation to changing climate conditions in Fairfield County, Connecticut.

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.

FAQ

About Samuel Bargh Reservoir Dam

Where does the data for Samuel Bargh Reservoir 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.
