Cyclone dam
Cyclone
Cyclone, located in Apache, Arizona, is a federal-owned dam managed by the Bureau of Indian Affairs. Built in 1965 for recreational purposes, this earth dam stands at a structural height of 52 feet with a length of 390 feet. It has a storage capacity of 775 acre-feet and is situated on the SAND CREEK river/stream.
With a hazard potential rated as high and a risk assessment indicating very high risk, Cyclone poses significant challenges in terms of emergency preparedness and risk management. While the dam's condition assessment is currently not available, regular inspections are conducted every five years to ensure its safety and integrity. Despite the lack of certain data points, the dam's primary purpose for recreation highlights its importance in providing water resources for the surrounding area.
As climate enthusiasts, understanding the intricacies of Cyclone's design and operation can shed light on the critical role it plays in water resource management in Arizona. With a controlled spillway and a high-risk designation, it is evident that the dam requires vigilant monitoring and maintenance to mitigate potential risks. The involvement of the Bureau of Indian Affairs in all aspects of the dam's ownership, funding, design, construction, regulation, inspection, and operation underscores the federal government's commitment to managing water resources effectively in the region.
Dam data reference
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 Cyclone
Where does the data for Cyclone 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 High 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.
