Summary

Completed in 1995, this earth dam boasts a height of 8.7 feet and a hydraulic height of 6.3 feet, with a length of 590 feet. Managed by the local government, the dam is state regulated and inspected, ensuring its structural integrity and safety in preventing potential flooding in the area.

With a low hazard potential and satisfactory condition assessment, the Leavenworth Detention Pond Dam serves as a reliable barrier against flooding, offering a storage capacity of 96 acre-feet. The uncontrolled spillway with a width of 10 feet further enhances its flood risk reduction capabilities. Despite its moderate risk assessment, the dam's risk management measures and emergency preparedness remain up to date, providing a sense of security to residents in the Oakland County area.

Overall, the Leavenworth Detention Pond Dam stands as a testament to effective flood risk reduction efforts in Michigan. With its strategic location and design, the dam plays a vital role in protecting the surrounding community from potential inundation, showcasing the importance of proactive infrastructure management in the face of changing climate patterns and water resource challenges.

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.
