Summary

Standing at a height of 32 feet, this dam serves as a crucial structure along the TR-Missouri River, providing a storage capacity of 51 acre-feet and a drainage area of 110 acres. With a normal storage capacity of 40 acre-feet, this dam has a surface area of 3 acres and is classified as having a high hazard potential.

Despite its important role in water resource management, Dead Mans Hole Dam has not been rated for its condition assessment, and its emergency action plan status remains unknown. The dam has not undergone recent inspections, and there is limited information available on its construction history. The dam's hazard potential underscores the importance of regularly assessing its safety and implementing risk management measures to ensure the protection of downstream communities and ecosystems.

In the absence of state regulation and inspection, it is imperative for the owners of Dead Mans Hole Dam to prioritize safety measures and ensure the dam's structural integrity. With its high hazard potential and proximity to the Missouri River, this dam plays a critical role in flood control and water supply management. It is essential for the owners to collaborate with relevant agencies and experts to develop and implement a comprehensive emergency action plan to mitigate risks and safeguard the surrounding area from potential dam failures.

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.
