Summary
With a length of 3400 feet and a storage capacity of 70 acre-feet, it serves as a crucial structure on the TR-MONTEZUMA CR river system. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular state inspections and enforcement measures to ensure its safety and compliance with regulatory standards.
Despite its relatively small surface area of 2 acres, Oknoname 111036 poses a significant risk, with a hazard potential classified as "Undetermined" and a condition assessment marked as "Unsatisfactory." The dam's risk assessment indicates a very high risk level, emphasizing the need for thorough monitoring and maintenance. The presence of a controlled spillway and a single valve outlet gate highlights the dam's design features for managing water flow and mitigating potential risks. Efforts to improve the dam's condition and emergency preparedness are crucial in safeguarding the surrounding community and environment from the potential impacts of a dam failure.
Markwayne Mullin, the representative for Oklahoma's 2nd Congressional District, oversees the area where Oknoname 111036 is located. As a part of the Tulsa District under the U.S. Army Corps of Engineers (USACE), the dam is subject to state and federal regulations to ensure its integrity and safety. With its historical significance dating back to the early 20th century, Oknoname 111036 serves as a vital component of the region's water resource infrastructure, highlighting the importance of proactive management and maintenance to prevent potential disasters and ensure long-term sustainability in the face of changing climate conditions.

Dam Data Reference
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.
