Summary

With a height of 20 feet and a length of 1100 feet, the dam provides a storage capacity of 284 acre-feet, with a normal storage level of 117 acre-feet. The primary purpose of the dam is listed as "Other", with no spillway in place.

Although the dam is not state-regulated, it is subject to state permitting and inspection requirements. The hazard potential of the dam is not available, but the risk assessment categorizes it as high. Despite its condition being listed as "Not Rated", the dam has one outlet gate and is currently not considered to be a hazard. The surrounding area covers a surface area of 17 acres and has not been associated with any incidents or emergencies.

Overall, Apache Ranch Lake Dam serves as a vital structure for water resource management in the area, ensuring water storage and management for various purposes. Its unique design and construction date add to its historical significance, while ongoing state oversight and inspection processes help to maintain its safety and functionality for the community and environment.

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.
