Summary
Built in 1960, this earth dam stands at a height of 30 feet and serves a primary purpose of "Other." It has a storage capacity of 400 acre-feet and a normal storage level of 70 acre-feet, with a maximum discharge capacity of 1820 cubic feet per second. The dam spans 310 feet in length and is regulated by the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place.
Despite being classified as having a low hazard potential, Oknoname 051045 is considered to have a very high risk due to its location and surrounding factors. The dam features a controlled spillway with a width of 1 foot and is equipped with a valve outlet gate. The last inspection of the dam took place in August 2010, with a scheduled inspection frequency of every 5 years. While the condition assessment is currently marked as "Not Rated," the dam's risk management measures and emergency action plan status remain unspecified. With its strategic position on TR-W Bitter Creek and close proximity to Chickasha, water resource and climate enthusiasts may find Oknoname 051045 to be a notable structure within the Tulsa District 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.
