Summary

Completed in 1945, this earth dam stands at a height of 18 feet with a length of 466 feet, providing a storage capacity of 899 acre-feet and a surface area of 104 acres. The primary purpose of Eagar-Slade is to support fire protection, stock, small fish, irrigation, and fish and wildlife activities in the area.

With a low hazard potential and a moderate risk assessment rating, Eagar-Slade has not been assigned a DSAC date and has not been assessed for condition. The dam features an uncontrolled spillway and outlet gates, with a maximum discharge capacity of 736 cubic feet per second. While last inspected in July 2011 with a scheduled inspection frequency of 5 years, the dam's emergency action plan status, inundation maps preparation, and risk management measures remain unspecified. Despite these gaps, Eagar-Slade stands as a critical water resource structure in Apache County, Arizona, serving as a valuable habitat for wildlife and supporting various water-related activities in the region.

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.
