Summary
Built in 1970, this 22-foot high structure serves multiple purposes, with a primary focus on water resource management. The dam has a storage capacity of 200 acre-feet, with a normal storage level of 70 acre-feet and a surface area of 5 acres.
Managed by the Oklahoma Water Resources Board (OWRB), Oknoname 111016 has a low hazard potential and a very high risk assessment rating. Despite being in good condition and not rated for assessment, the dam has undergone regular inspections, with the latest one conducted in August 2011. The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge capacity of 450 cubic feet per second.
Overall, Oknoname 111016 plays a crucial role in the water management infrastructure of Okmulgee County, providing essential flood control and water storage capabilities. With its strategic location and efficient design, this dam serves as a vital asset for the local community and contributes to the overall resilience of the region's water resources amidst the challenges posed by climate change.

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.
