Summary
The earth dam stands at a height of 11 feet and spans 200 feet in length, with a storage capacity of 275 acre-feet. Situated on Browns Brook, the dam plays a crucial role in maintaining the local ecosystem and water resources in the area.
Managed by the Connecticut Department of Energy and Environmental Protection (DEEP), Sessions Meadow Marsh Dam is regulated, inspected, and enforced by the state to ensure its structural integrity and compliance with safety standards. With a low hazard potential, the dam poses minimal risk to surrounding communities. Though its condition has not been formally rated, regular inspections are conducted to assess its maintenance needs and operational effectiveness.
Despite its modest size, Sessions Meadow Marsh Dam plays a significant role in supporting wildlife habitat and regulating water flow in the region. As climate change continues to impact water resources, the dam's importance in preserving biodiversity and ensuring water security for future generations becomes increasingly vital.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
