Summary
The lake was built in 1946 as part of a flood control and irrigation project. Its primary purpose is to provide water for irrigation, but it is also used for recreational activities such as fishing, boating, camping, and hiking.
The hydrology of Lake Altus is primarily fed by the North Fork of the Red River and Elm Creek, which are both located in the Wichita Mountains. The lake's surface area is approximately 6,260 acres, and its maximum depth is 118 feet. The average depth of the lake is around 40 feet.
Lake Altus is heavily dependent on snowpack and rain for its water supply. The lake receives water from various sources, including the snowmelt from the Wichita Mountains and precipitation from surrounding areas. Agricultural use of the water from the lake is also significant, with the water used for irrigation in the surrounding farmland.
In summary, Lake Altus at Lugert is a man-made reservoir built for flood control and irrigation purposes. It is primarily fed by the North Fork of the Red River and Elm Creek, and its water supply is dependent on snowpack and rain. The lake is also used for recreational activities and agricultural use.

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.
