Summary
Completed in 1970, this dam stands at a height of 25 feet and stretches 3250 feet in length, with a storage capacity of 50 acre-feet. The dam serves a primary purpose classified as "Other" and is regulated by the Oklahoma Water Resources Board (OWRB), with state permitting, inspection, and enforcement in place.
Despite being classified as having low hazard potential, Oknoname 111061 is considered to have a very high risk due to various factors. The dam features a controlled spillway with a width of 1 foot and a single valve outlet gate. Although the condition assessment is marked as "Not Rated," the last inspection conducted in August 2011 indicated a 5-year inspection frequency. The risk management measures and emergency action plan status for this dam remain unspecified, highlighting a potential area for improvement to ensure the safety and integrity of the structure.
Located within the Tulsa District, this dam falls under the jurisdiction of the Oklahoma state regulatory agency and operates under the guidance of the primary source agency in Oklahoma. With Markwayne Mullin as the congressional representative for this district, stakeholders and water resource enthusiasts are encouraged to monitor the risk assessment and management of Oknoname 111061 to uphold the safety standards and environmental protection of the surrounding area.

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.
