Summary

Built in 1980 by designer David P. Miller, the dam stands at a height of 27 feet and spans a length of 900 feet, providing a storage capacity of 115 acre-feet. Situated on the Ant Hollow Draw river or stream, Hickey serves multiple purposes including fire protection, stock watering, and small fish pond management.

Despite its low hazard potential, Hickey is currently assessed as being in poor condition as of the last inspection in October 2018. The dam features an uncontrolled spillway, one valve outlet gate, and a hydraulic height of 22 feet. The risk assessment for Hickey is moderate (3), indicating a need for ongoing monitoring and potential risk management measures to ensure the safety and integrity of the structure.

For water resource and climate enthusiasts, Hickey presents an intriguing case study in dam management and maintenance. With its location in a critical watershed area in Wyoming and its role in supporting agricultural irrigation, the condition and functionality of Hickey have significant implications for water security and resource management in the region. Ongoing assessments and potential risk mitigation efforts will be vital to safeguarding this important infrastructure for the future.

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.
