About this dam

Bulls Bridge Forebay Dike

Bulls Bridge Forebay Dike, located in Gaylordsville, Connecticut, is a crucial structure designed for hydroelectric purposes along the Housatonic River. Built in 1903, this earth dam stands at a height of 39 feet and spans 650 feet in length, with a storage capacity of 400 acre-feet. The dam serves as a significant component in managing the water resources of the region, with a maximum discharge capacity of 1250 cubic feet per second.

Managed by the Federal Energy Regulatory Commission, Bulls Bridge Forebay Dike also caters to recreational activities in addition to its primary hydroelectric function. The dam's spillway, which is uncontrolled, has a width of 32 feet, ensuring effective water flow management during times of excess water. Despite its age, the dam's hazard potential is deemed significant, and regular inspections are conducted to ensure its structural integrity and safety.

With a moderate risk assessment rating, Bulls Bridge Forebay Dike plays a vital role in water resource management in Litchfield County, Connecticut. Its historical significance, combined with its functional importance for hydroelectricity generation and recreation, underscores the need for ongoing monitoring and maintenance to ensure the safety and reliability of this essential infrastructure.

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 Bulls Bridge Forebay Dike

Where does the data for Bulls Bridge Forebay Dike 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.
