Summary
It spans a length of 409 feet and has a maximum storage capacity of 145.75 acre-feet, serving a drainage area of 2.12 square miles along the Deadman Creek of South Canadian River.
Despite being labeled as a low hazard potential structure with a "Very High (1)" risk assessment, Oknoname 30244 is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular state inspections and enforcement to ensure its safety. The dam features a controlled spillway type with a width of 1 foot and is equipped with a valve outlet gate for water release. With a surface area of 8.2 acres and a normal storage capacity of 78.11 acre-feet, this dam plays a crucial role in managing water resources in the region.
Although the dam's condition assessment is listed as "Not Rated," Oknoname 30244 has not been modified since its completion. The last inspection was conducted in September 2010, with a scheduled inspection frequency of 5 years. While emergency action plans and risk management measures are not explicitly mentioned, the dam's presence and functionality contribute significantly to water resource management and climate resilience efforts in the area, under the jurisdiction of the OWRB and Tulsa District of the US Army Corps of Engineers.

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.
