Summary
Built in 2003 by the designer Golder, this buttress dam stands at a height of 86.5 feet and has a storage capacity of 3,422 acre-feet. With a surface area of 138 acres, the dam serves the primary purpose of storing tailings from mining activities.
Despite its satisfactory condition assessment as of 2017, the Ira Holliman Tailings Impoundment Dam poses a high hazard potential due to its uncontrolled spillway and outlet gates. The dam has a moderate risk rating, indicating that it may require ongoing risk management measures to ensure the safety of surrounding communities and the environment. Regular inspections are conducted every 2 years to monitor the dam's integrity and address any potential issues that may arise.
As water resource and climate enthusiasts, it is crucial to monitor the Ira Holliman Tailings Impoundment Dam and other similar structures to prevent potential hazards and protect the surrounding ecosystems. By staying informed about the dam's condition and risk assessment, stakeholders can work towards implementing effective risk management measures and emergency preparedness plans to mitigate any potential threats posed by the dam.

Dam Data Reference
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.
