Summary

Built in 1945, this Federal-owned structure serves primarily for irrigation purposes, with a maximum storage capacity of 168,120 acre-feet and a surface area of 6,260 acres. The dam stands at a height of 25 feet, with a hydraulic height of 18 feet and a structural height of 35 feet, making it a crucial water resource for the region.

With a high hazard potential and a very high risk assessment rating, Altus East Dike is a significant part of water management in the area. The dam features a controlled spillway, one valve outlet gate, and has a maximum discharge capacity of 57,200 cubic feet per second. Despite not having a condition assessment rating, the dam's emergency action plan status and risk management measures are not specified, raising concerns about its safety and potential impact on the surrounding community in the event of a failure. As the dam has not been inspected since 1992, there is a pressing need for updated assessments and maintenance to ensure the continued safety and reliability of this critical water 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.
