Summary
This earth dam, with a height of 41.7 feet and a length of 744 feet, serves a primary purpose that is classified as "Other." The dam has a storage capacity of 338 acre-feet and a surface area of 22.7 acres, providing essential water resource management for the surrounding area.
Despite its low hazard potential, the dam at Zonia Southwest Holding Tank is subject to regular state inspections, with the last one conducted in May 2012. The risk assessment for this structure is moderate, highlighting the importance of ongoing monitoring and risk management measures. With a spillway width of 43 feet and uncontrolled spillway type, the dam is designed to handle moderate discharge events and minimize the risk of flooding in French Gulch - TR, the associated river or stream.
For water resource and climate enthusiasts, Zonia Southwest Holding Tank presents an intriguing case study of private ownership, state regulation, and risk management in the realm of water infrastructure. With its location in Yavapai County, Arizona, this earth dam plays a crucial role in water storage and management, emphasizing the importance of sustainable practices and proactive maintenance to ensure the safety and reliability of our water resources in the face of changing climate conditions.

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.
