Summary
Owned by the local government and regulated by the Department of Conservation and Recreation, this earth dam stands at a height of 10 feet with a hydraulic height of 8 feet. The dam serves a primary purpose as a fish and wildlife pond, providing a storage capacity of 50 acre-feet and covering a surface area of 41.9 acres.
With a drainage area of 2.35 square miles, Lower Chandler Pond Dam plays a significant role in managing water flow and maintaining the ecological balance of the region. Despite its satisfactory condition assessment as of May 2015, the dam poses a significant hazard potential, highlighting the importance of regular inspections and maintenance. The dam's spillway type is uncontrolled, emphasizing the need for effective risk management measures to mitigate potential flooding risks and ensure the safety of the surrounding community.
In the event of an emergency, it is essential for the authorities to have an Emergency Action Plan (EAP) in place to guide response efforts. With a moderate risk assessment rating of 3, it is crucial for stakeholders to stay vigilant and prepared to address any potential threats posed by the dam. Lower Chandler Pond Dam stands as a critical infrastructure piece in the conservation and recreation efforts of the area, underscoring the importance of sustainable water resource management practices for the benefit of both wildlife and local communities.

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.
