Summary

Built in 1984 by USDA NRCS, this dam stands at a height of 25 feet with a storage capacity of 50 acre-feet. Despite its low hazard potential, it has a very high risk assessment rating, indicating the need for careful monitoring and management.

The dam is regulated by the Oklahoma Water Resources Board (OWRB), with state permitting, inspection, and enforcement in place. Its spillway is controlled with a width of 1 foot, and it is equipped with a valve outlet gate. While the dam's condition assessment is currently not rated, its last inspection in 2005 highlighted the need for regular monitoring and maintenance to ensure its safety and longevity.

Fuqua Evan K plays a crucial role in water resource management in the region, serving purposes beyond flood control and irrigation. Its location within the Tulsa District and its association with the Natural Resources Conservation Service underscore its importance in sustainable water management practices. Climate and water resource enthusiasts will find this dam's profile intriguing, given its unique design features and regulatory framework in place.

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.
