Summary
Completed in 1940, this earth dam structure stands at a height of 14 feet, with a hydraulic height and structural height matching that measurement. The reservoir has a normal storage capacity of 2,500 acre-feet, offering a surface area of 140 acres to support the water supply needs of the region.
With a significant hazard potential and a fair condition assessment as of the last inspection in June 2018, Altus Reservoir serves as a crucial water resource for the area. The controlled spillway, with a width of 4 feet, ensures proper water management during high-flow events. Despite its age, the dam continues to meet regulatory standards for inspection, enforcement, and permitting, highlighting the commitment to maintaining the integrity of this essential infrastructure.
While the risk assessment indicates a very high level of risk, the management of Altus Reservoir includes emergency preparedness measures such as a valve outlet gate and a designated inspection frequency of every three years. The reservoir's location on the North Fork Red River underscores its importance as a key source of water supply in the region, catering to the needs of both residents and the local environment.

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.
