Summary

This earth-type dam stands at 16 feet tall and spans 400 feet in length, holding a storage capacity of 890 acre-feet. Situated on the Slovik Branch river, the dam has a spillway width of 19 feet and a maximum discharge rate of 550 cubic feet per second.

Despite being classified as having a significant hazard potential, the dam is currently in fair condition as of its last assessment in June 2016. The dam is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP), with state-permitting, inspection, and enforcement protocols in place. The risk assessment for Halls Pond Dam is moderate, indicating a level 3 risk, although specific risk management measures are not detailed in the available data.

Water resource and climate enthusiasts may be drawn to Halls Pond Dam for its role in providing recreational opportunities while also raising awareness about the importance of dam safety and maintenance. With its historical significance and ongoing regulatory oversight, the dam serves as a focal point for both local communities and regulatory agencies in ensuring the safety and sustainability of water resources in the area.

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.
