Summary

Built in 1902, this concrete gravity dam stands at a height of 24 feet and stretches 203 feet in length, with a storage capacity of 400 acre-feet. The dam serves multiple purposes, including hydroelectric power generation and recreational activities, making it a crucial asset in the region.

Managed by a public utility, Bulls Bridge is regulated by the Federal Energy Regulatory Commission and undergoes regular inspections to ensure its safe operation. With a low hazard potential and moderate risk assessment, the dam plays a vital role in water resource management and climate resilience in the area. Its historical significance and engineering marvel continue to attract water resource and climate enthusiasts, offering a fascinating glimpse into the intersection of technology and nature.

As a key landmark in Litchfield County, Connecticut, Bulls Bridge symbolizes the harmonious coexistence of human ingenuity and environmental stewardship. Its uncontrolled spillway, with a width of 195 feet, serves as a testament to the innovative engineering techniques of its time. With a rich history and ongoing contributions to the local community, Bulls Bridge remains a beacon of sustainable water resource management and a reminder of the importance of preserving our natural resources for future generations to enjoy.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
