Summary

With a height of 34 feet and a storage capacity of 28 acre-feet, the dam serves as a crucial water resource for the surrounding area. Although the dam has an uncontrolled spillway type and a low hazard potential, its risk assessment is rated as moderate (3), highlighting the importance of ongoing monitoring and maintenance to ensure its continued functionality.

Despite not being state-regulated or permitted, the Gardner dam plays a vital role in water management within the region. Its earth construction type and low hazard potential indicate a stable structure that contributes to the overall water infrastructure. With no associated structures and a relatively small storage capacity, the dam serves as a key component in the management of TR SAND CREEK, providing essential water storage and flood control benefits.

Managed by the Natural Resources Conservation Service, the Gardner dam represents a critical piece of the water resource puzzle in Woodward, Oklahoma. While its condition is currently rated as not assessed, the dam's moderate risk level underscores the need for proactive measures to ensure its long-term sustainability. As climate change continues to impact water resources, structures like the Gardner dam play a crucial role in adapting to evolving conditions and securing reliable water sources 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.
