Summary
This Earth-type dam stands at a height of 20.6 feet and has a storage capacity of 123.9 acre-feet, with a surface area of 29.3 acres. The dam is regulated by the Arizona Department of Water Resources and undergoes regular inspections to ensure its safety and compliance with state regulations.
Despite its low hazard potential, Broken Tank poses a moderate risk due to its condition assessment being marked as "Not Rated." The dam's spillway type is uncontrolled, with a width of 70 feet, and it has not been modified in recent years. The last inspection took place in June 2019, with an inspection frequency of 5 years. While an Emergency Action Plan (EAP) has not been prepared or updated, the risk management measures for this structure are currently unspecified.
Water resource and climate enthusiasts may find Broken Tank intriguing due to its unique location and purpose, serving as a vital source of water for fire protection and livestock in the Winslow area. With a moderate risk assessment and a state-regulated status, this dam presents an opportunity for further study and monitoring to ensure the safety of its surrounding community and ecosystem. As a key feature in the water infrastructure of Arizona, Broken Tank highlights the importance of maintaining and managing water resources in a sustainable and resilient manner.

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.
