Summary

Managed by the Natural Resources Conservation Service, this earth dam stands tall at a height of 60.6 feet, with a structural height of 68 feet, and a length spanning 985 feet. Completed in 1986, it serves the primary purpose of flood risk reduction along the Kings Creek, with a storage capacity of 3242 acre-feet and a normal storage of 192 acre-feet.

Despite its high hazard potential, Upper Petit Jean Wid Site 5 has not been rated for its condition assessment as of yet. The dam boasts a moderate risk assessment level of 3, indicating a need for continued monitoring and risk management measures. The last inspection took place in December 2015, highlighting the importance of regular assessments to ensure the safety and effectiveness of this vital water resource infrastructure. For water resource and climate enthusiasts, this site offers a fascinating glimpse into the intersection of engineering, environmental conservation, and community resilience in the face of natural disasters.

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.
