Summary
This structure stands at a hydraulic height of 30 feet with a structural height of 50 feet and a length of 900 feet, providing a storage capacity of 900 acre-feet. While it has not been rated for condition assessment, its hazard potential is considered low, and it is inspected every 5 years.
Managed by the Bureau of Land Management, the Upper Centennial Control Structure plays a crucial role in protecting the surrounding La Paz County from potential flooding events. Despite its primary purpose of flood risk reduction, it also serves as a key asset in the region's water resource management strategy. With its location on an offstream section of the Gila River, this structure showcases the innovative engineering efforts undertaken to mitigate natural disasters and safeguard communities in the area.
As a federal-owned and funded structure, the Upper Centennial Control Structure exemplifies the collaboration between government agencies to address climate-related challenges. Its strategic design and construction by the Bureau of Land Management demonstrate a commitment to environmental stewardship and disaster resilience in the face of evolving climate patterns. This control structure stands as a testament to the importance of water resource management and climate adaptation efforts in safeguarding communities and ecosystems from the impacts of extreme weather events.

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.
