Summary
Station Reservoirs A, located in Apache County, Arizona, is a vital water resource managed by a public utility. This reservoir, completed in 1984, has a storage capacity of 206 acre-feet and serves as a key component of the state's water infrastructure. Situated along Carrizo Wash, this earth dam stands at a height of 12 feet and spans a length of 5100 feet, providing essential water supply and storage for the region.
Despite its low hazard potential, Coronado Gen. Station Reservoirs A is subject to regular inspections and regulatory oversight by the Arizona Department of Water Resources. With a risk assessment rating of 'High (2)', the reservoir is an important feature of the state's water management system. Although the dam's condition assessment is currently 'Not Rated', ongoing maintenance and monitoring ensure the safety and reliability of this critical water storage facility for the surrounding area.
Coronado Gen. Station Reservoirs A plays a crucial role in water resource management for Apache County, Arizona. As part of the state's regulated infrastructure, this reservoir provides essential water storage and supply capabilities. With its low hazard potential and high risk assessment rating, the dam is carefully monitored and maintained to ensure the safety and security of the surrounding community.

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.
