Summary
Built in 1968, this dam serves multiple purposes and stands at a height of 22 feet with a length of 1060 feet. The dam has a storage capacity of 220 acre-feet and a normal storage level of 165 acre-feet, making it essential for water resource management in the area.
Managed by the Oklahoma Water Resources Board, Oknoname 087036 has a controlled spillway and a low hazard potential. Despite being in good condition and meeting regulatory standards, the dam has a very high risk assessment due to its age and potential impact in case of failure. The last inspection was conducted in 2005, with a scheduled inspection frequency of every 5 years to ensure its safety and stability for both water management and climate resilience in the region.
With its location on the TR-Walnut Creek and under the jurisdiction of the Tulsa District of the US Army Corps of Engineers, Oknoname 087036 plays a vital role in flood control and water supply for the surrounding area. As climate change continues to impact water resources, the maintenance and management of dams like Oknoname 087036 are crucial for sustainable water use and adaptation to changing climate conditions in Oklahoma.

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.
