Summary
Standing at 30 feet in height with a length of 400 feet, this dam provides a storage capacity of 360 acre-feet and a surface area of 11 acres. It is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with a low hazard potential and a very high risk assessment rating.
Despite its humble size, Oknoname 047007 plays a crucial role in mitigating flood risks in the Pond Creek area. Its controlled spillway and valve outlet gate ensure efficient water management, with a maximum discharge capacity of 2700 cubic feet per second. The dam's stone core and soil foundation attest to its sturdy construction, while its state-regulated status underscores its importance in maintaining water resource integrity in the region.
As an integral part of the local water infrastructure, Oknoname 047007 symbolizes the collaborative efforts between private owners, federal agencies, and state regulators in safeguarding communities from flooding events. With its history of service dating back to 1960 and adherence to inspection protocols, this dam stands as a testament to effective flood risk reduction measures and responsible water resource management in the heart of Oklahoma.

Dam Data Reference
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.
