Summary

Completed in 2015, this Earth dam stands at a height of 40 feet and spans a length of 850 feet, with a primary purpose of water supply. With a storage capacity of 20,800 acre-feet and a surface area of 650 acres, Mcintosh Reservoir Dam plays a crucial role in water resource management for the region.

The dam's high hazard potential is mitigated by its satisfactory condition assessment, last conducted in February 2016. Despite its moderate risk level, emergency preparedness measures such as an Emergency Action Plan (EAP) are yet to be fully implemented. The dam's uncontrolled spillway and outlet gates present challenges in managing potential risks, underscoring the importance of regular inspections and enforcement to ensure the safety and reliability of the structure for both water supply and flood control purposes.

Mcintosh Reservoir Dam not only serves as a key water supply source but also as a critical component in the region's infrastructure for managing water resources and mitigating flood risks. As climate change continues to impact water availability and extreme weather events, the importance of maintaining and enhancing the resilience of structures like Mcintosh Reservoir Dam becomes increasingly evident. Collaboration between local and state agencies will be essential in ensuring the continued safety and effectiveness of this important water resource infrastructure.

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.
