Summary

Standing at a height of 20 feet, this Earth dam with a buttress core serves as a barrier on TR Middle River, providing a storage capacity of 268 acre-feet and covering a surface area of 25 acres. With a drainage area of 446 square miles, the dam plays a crucial role in water resource management in the region.

Despite its recreational focus, Reeds Lake Dam is classified as having a high hazard potential, although its condition assessment is currently labeled as "Not Rated." The dam has not been inspected in recent years, and there is no Emergency Action Plan (EAP) in place. However, the dam's historical significance and environmental impact on the surrounding area underscore the need for ongoing monitoring and evaluation to ensure the safety and sustainability of this important water resource infrastructure.

With its picturesque location and significant storage capacity, Reeds Lake Dam stands as a reminder of the intersection between human development and natural resources. As climate change continues to impact water availability and quality, the proper management and maintenance of dams like Reeds Lake Dam are critical for ensuring the safety of communities downstream and the preservation of this vital water source for future generations of water resource and climate enthusiasts alike.

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.
