Coronado Gen. Station Reservoirs A dam
Coronado Gen. Station Reservoirs A
Coronado Gen. 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
- 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.
- 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.
- 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.
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, environmental 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.

About Coronado Gen. Station Reservoirs A
Where does the data for Coronado Gen. Station Reservoirs A come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
