Summary
Completed in 1945, this Earth-type dam on the Red River stands at an impressive height of 46 feet and spans 330 feet in length, serving primarily for irrigation purposes. With a maximum storage capacity of 168,120 acre-feet and a normal storage level of 134,495 acre-feet, the dam covers a surface area of 6,260 acres and handles a drainage area of 2,515 square miles.
The dam's spillway, controlled with a width of 300 feet, ensures efficient water discharge during high flow events. Despite its high hazard potential, Altus South Dike's condition assessment is currently listed as "Not Available," emphasizing the need for regular inspection and maintenance. The structure is part of a network of five associated structures within the area, managed by the Bureau of Reclamation. With its strategic location and significant contribution to irrigation and water management in the region, Altus South Dike remains a key component in ensuring water resource sustainability and climate resilience in Kiowa County, Oklahoma.
Water resource and climate enthusiasts will appreciate the engineering and operational aspects of Altus South Dike, which plays a crucial role in water storage and management on the Red River. The dam's historical significance, coupled with its modern-day challenges in terms of risk assessment and emergency preparedness, highlights the importance of continued monitoring and maintenance to safeguard the surrounding communities and agricultural lands. As part of the Bureau of Reclamation's portfolio, Altus South Dike exemplifies the intersection of infrastructure, water resources, and environmental stewardship, making it a compelling subject for further study and engagement in the realm of water resource management and climate adaptation.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
