Summary

Completed in 1998 by the US Army, this dam stands at a height of 24 feet and has a length of 897 feet, providing a storage capacity of 224 acre-feet. Its primary purpose and design are to control water flow through an uncontrolled spillway, with a spillway width of 40 feet.

Despite being classified as having a low hazard potential and moderate risk assessment, Dam 24 has not undergone a recent condition assessment. However, it is regularly inspected every four years, with the last inspection conducted in September 2020. The dam does not fall under state jurisdiction or regulation, with all aspects of ownership, funding, design, construction, regulation, inspection, and operation being handled by the US Army.

For water resource and climate enthusiasts, Dam 24 serves as a crucial infrastructure component in managing water flow and storage in the region. Its location in a non-regulated state highlights the federal government's role in maintaining and operating such critical structures. Despite its low hazard potential, the moderate risk assessment underscores the importance of regular inspections and maintenance to ensure the dam's safety and reliability in the face of changing climate conditions.

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.
