Summary
Built in 1940, the dam stands at 15 feet high with a hydraulic height of 11 feet and a length of 300 feet. Its primary purpose is flood risk reduction along the TR East Cache Creek, with a storage capacity of 51 acre-feet and a normal storage level of 40 acre-feet. The dam has a controlled spillway and features a valve outlet gate for water release.
Despite being classified as having a low hazard potential, Oknoname 033007 is rated as having a very high risk due to its condition assessment being labeled as "Not Rated." The dam is regulated by the Oklahoma Water Resources Board, with state jurisdiction and permitting in place for inspection and enforcement. The surrounding area of Cotton County, Oklahoma, is prone to flooding, making the flood risk reduction function of the dam crucial for protecting the local community and infrastructure along the TR East Cache Creek.
With a congressman representative of Tom Cole (R) and situated within the Fort Worth District of the US Army Corps of Engineers, Oknoname 033007 plays a vital role in water resource management and climate resilience efforts in the region. As enthusiasts of water resources and climate, understanding the significance of this dam in mitigating flood risks and ensuring the safety of the surrounding area is essential for advocating for its proper maintenance and inspection to prevent any potential disasters.

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.
