Summary

With a height of 12 feet and a length of 450 feet, the dam serves multiple purposes including flood control and water storage. It has a normal storage capacity of 176 acre-feet and covers a surface area of 20 acres, with a drainage area of 377 square miles.

The dam is privately owned and regulated by the Connecticut Department of Energy and Environmental Protection (DEEP). It has been inspected for safety and maintenance, with the last assessment in June 2017 rating its condition as fair. The dam features slide gates for water release and has a spillway width of 200 feet. Classified as having a significant hazard potential, the Rogers Corporation Dam plays a crucial role in managing water resources in the region and protecting against potential risks associated with its operations.

Overall, the Rogers Corporation Dam stands as a significant infrastructure element in the water management system of Connecticut, ensuring the safety of the surrounding community and supporting environmental conservation efforts along the Quinebaug River. Its historical significance, combined with its functional importance in flood control and water storage, underscores the vital role it plays in balancing the needs of water resource management and climate resilience in the region.

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.
