Summary

4) in Maricopa, Arizona, is a local government-owned facility that serves as a crucial flood risk reduction structure along the Verde River. Completed in 1973, this earth dam stands at 36.5 feet in structural height, with a hydraulic height of 20 feet and a dam height of 20 feet. The dam spans 633 feet in length and has a storage capacity of 344 acre-feet, providing protection to the surrounding area from potential inundation during periods of high discharge.

Managed by the Arizona Department of Water Resources, Golden Eagle Park (No. 4) boasts a spillway width of 356 feet and a surface area of 16.8 acres. Despite its high hazard potential, the dam is currently in satisfactory condition, with a moderate risk assessment rating. Regular inspections ensure its continued effectiveness in flood risk mitigation, with the last assessment conducted in December 2020. With a drainage area of 7.13 square miles, the dam plays a vital role in safeguarding the community of Fountain Hills from the impacts of flooding, highlighting its importance in water resource management and climate resilience efforts in the region.

Situated in a picturesque location and designed to withstand the challenges posed by the surrounding environment, Golden Eagle Park (No. 4) stands as a testament to the effective collaboration between local government agencies and regulatory bodies in ensuring the safety and well-being of residents. With its strategic placement along the Verde River and adherence to rigorous inspection and maintenance protocols, this earth dam continues to serve as a vital infrastructure for flood risk reduction in Maricopa County. As water resource and climate enthusiasts, we can appreciate the intricate design and functionality of this essential piece of infrastructure, which plays a crucial role in protecting the community from the unpredictable forces of nature.

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. 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

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, 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.
