Nearby: Windsorville Pond Dam Shepard's Dam
Last Updated: February 23, 2026
The Broad Brook Mill Pond Dam, located in East Windsor, Connecticut, was completed in 1880 and serves as a recreational area for water resource and climate enthusiasts.
Summary
The dam is owned by the local government and is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP). With a height of 21 feet and a length of 193 feet, the dam holds a maximum storage capacity of 130 acre-feet and covers a surface area of 23 acres.
The dam has a significant hazard potential and is currently in a condition that has not been rated. It has a spillway width of 81 feet and a maximum discharge of 2500 cubic feet per second. Despite not having a current condition assessment, the dam is subject to regular inspections every 7 years to ensure its safety and compliance with state regulations. The Broad Brook Mill Pond Dam is a historic structure that continues to provide opportunities for recreation and enjoyment in the Hartford, Connecticut area.
Overall, the Broad Brook Mill Pond Dam stands as a testament to the importance of maintaining and managing water resources for both functional and recreational purposes. As a masonry dam with a long history of service, it represents a vital part of the local landscape and an essential component of the region's water infrastructure. For water resource and climate enthusiasts, the dam serves as a reminder of the delicate balance between human development and environmental conservation in the face of changing climate patterns and increasing water demands.

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.
