About this dam

Stewarts Bridge

Stewarts Bridge in Saratoga, New York, is a significant hydroelectric structure on the Sacandaga River, completed in 1952. This dam, standing at 112 feet high and 1860 feet long, serves multiple purposes such as hydroelectric power generation and recreation. With a storage capacity of 18,600 acre-feet and a drainage area of 1054 square miles, Stewarts Bridge plays a crucial role in water resource management in the region.

Managed by the Federal Energy Regulatory Commission, Stewarts Bridge is subject to regular inspections to ensure its safety and functionality. The dam has a controlled spillway with a width of 250 feet and is equipped with five Tainter gates. Due to its high hazard potential and very high risk assessment, risk management measures are in place to mitigate any potential threats. Stewarts Bridge embodies the intersection of water resource management, climate resilience, and energy production in the region, making it a vital infrastructure for both environmental and economic sustainability.

As a key component of the New York District's water infrastructure, Stewarts Bridge underscores the importance of sustainable water resource management and climate adaptation efforts. With its historic significance and modern functionality, this dam stands as a testament to the ongoing commitment to balancing the needs of energy production, recreation, and environmental protection. As climate change continues to impact water resources, structures like Stewarts Bridge play a critical role in ensuring the resilience and sustainability of our water systems for future generations.

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 Stewarts Bridge

Where does the data for Stewarts Bridge 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.
