Summary
Built in 1970, this dam stands at a height of 22 feet and has a storage capacity of 188 acre-feet. With a controlled spillway and one outlet gate, the dam's hazard potential is rated as low, but its risk assessment is classified as very high (1).
Despite being a privately owned structure, Oknoname 013005 falls under the regulatory jurisdiction of the Oklahoma Water Resources Board (OWRB), with state permitting, inspection, and enforcement mechanisms in place. The dam has not been rated for its condition assessment, but it undergoes inspection every 5 years, with the last one conducted in September 1999. Although emergency action plans and risk management measures are not specified, the dam's risk assessment suggests a need for heightened vigilance and preparedness.
Markwayne Mullin represents the Fort Worth District where Oknoname 013005 is situated, although specific federal funding, design, construction, or regulatory agencies associated with the dam are not mentioned. With its location in Shady Grove Sch. and its vital role in providing water for irrigation, this dam serves as a key resource for water management in the region, highlighting the intersection of private ownership, state regulation, and the importance of infrastructure maintenance in the face of climate variability.

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.
