Summary
Built in 1960, the dam stands at a height of 20 feet and spans 150 feet in length, with a storage capacity of 100 acre-feet. Despite being categorized as low hazard potential, the dam is subject to state regulation, permitting, inspection, and enforcement by the Oklahoma Water Resources Board (OWRB).
The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge capacity of 300 cubic feet per second. Its primary purpose is designated as "Other", with the structure primarily serving as a water resource management feature. The risk assessment for Oknoname 051043 indicates a very high risk level, necessitating thorough risk management measures to mitigate potential hazards and ensure the safety of the surrounding community and environment.
Though not federally owned or funded, Oknoname 051043 falls under the jurisdiction of the Tulsa District and is subject to regular inspections with a frequency of 5 years. The dam's condition assessment is currently listed as "Not Rated", highlighting the importance of continued monitoring and maintenance to uphold its structural integrity and operational effectiveness. With a rich history dating back to the 1960s, this dam serves as a critical component of water resource management in the Grady County area of Oklahoma.

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.
