Summary
Built in 1970, this earth dam stands at a height of 37.5 feet and provides a storage capacity of 125 acre-feet. The primary purpose of the dam is for recreation, with a normal storage level of 45 acre-feet and a surface area of 36 acres.
The dam, located on Lions Brook, has a spillway width of 38 feet and a maximum discharge capacity of 1985 cubic feet per second. With a hazard potential classified as significant and a condition assessment rated as fair, the dam is inspected every four years to ensure its safety and functionality. Although the risk assessment is moderate, the dam meets guidelines for emergency action plans, but specific risk management measures and inundation maps are yet to be prepared.
Overall, Chadwick Meadows Wildlife Ref Dam is a vital structure for water resource management and recreational activities in the area. With its regulated state jurisdiction and significant hazard potential, it serves as an important asset for the community while also requiring periodic inspections and risk assessments to maintain its safety and integrity for both wildlife and residents alike.

Dam Data Reference
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.
