Summary
3 is a vital water resource structure located in Maricopa, Arizona, owned by a Public Utility. This offstream pond is regulated by the Arizona Department of Water Resources, ensuring that it meets state permitting, inspection, and enforcement requirements. The dam, primarily made of earth and stone, stands at a height of 45 feet and stretches over 8,381 feet in length, serving a crucial purpose in water management.
With a high hazard potential and risk assessment rating of 2 (high), Palo Verde Evaporation Pond No. 3 requires regular inspections to maintain its satisfactory condition. The last inspection in June 2020 deemed the structure to be in good shape, with emergency preparedness measures yet to be fully developed. Despite facing potential risks, the pond's strategic location and design make it an essential component in water resource management in the region.
As a key element in the water infrastructure system, Palo Verde Evaporation Pond No. 3 plays a pivotal role in water conservation and evaporation control. Its presence ensures the efficient management of water resources in the area, highlighting the importance of maintaining and monitoring such structures to safeguard against potential hazards and ensure the continued sustainability of water sources in Arizona.

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.
