Summary
The dam stands at a height of 35 feet and has a length of 890 feet, providing a storage capacity of 380 acre-feet. It is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to state inspection, permitting, and enforcement. The dam's spillway type is 'Controlled' with a width of 2 feet, and it has a low hazard potential with a very high risk assessment rating.
Situated on TR-WEWOKA CREEK, Oknoname 133001 serves as a vital infrastructure for water resource management in the region. Despite its age, the dam has not been rated for its condition and has not undergone recent assessments or Emergency Action Plan (EAP) updates. While the dam is not owned or funded by federal agencies, it is crucial for flood control and water supply in the area. With its strategic location and importance for the community, ongoing monitoring and maintenance are essential to ensure the safety and efficiency of Oknoname 133001 in the face of climate change impacts and evolving regulatory standards.
As a significant structure in the Tulsa District, Oknoname 133001 faces the challenges of aging infrastructure and changing environmental conditions. With Kendra S. Horn (D) serving as the representative for the area, the dam's risk management measures and emergency protocols need to be regularly updated to meet guidelines and ensure public safety. The dam's presence highlights the intersection of water resource management, climate resilience, and regulatory oversight, making it a focal point for enthusiasts interested in sustainable infrastructure development and climate adaptation strategies in Oklahoma's water systems.

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.
