Summary
Constructed in 1969, this Earth-type dam stands at a height of 20 feet and has a length of 375 feet. It serves a primary purpose of "Other" and has a normal storage capacity of 40 acre-feet, with a maximum storage of 90 acre-feet. The dam is situated on the TR-BEAVER-CR river or stream and is regulated by the Oklahoma Water Resources Board.
Despite being rated as having a low hazard potential, Oknoname 031056 is considered to have a very high risk, with a DSAC assigned date marked as not available. The dam features a controlled spillway and a single valve outlet gate. While it has not undergone a recent condition assessment, the last inspection was conducted in September 2010, with an inspection frequency of every 5 years. The risk management measures for this dam are currently unspecified, with emergency action plans and inundation maps not prepared or updated.
Water resource and climate enthusiasts will find Oknoname 031056 to be an intriguing structure with its unique design and location in the state of Oklahoma. The dam's presence on the TR-BEAVER-CR river highlights its importance in managing water resources within the region. With its low hazard potential but high risk assessment, there is a need for continued monitoring and potential updates to ensure the safety and integrity of this Earth-type dam. Further exploration into the risk management measures and emergency preparedness for Oknoname 031056 could provide valuable insights for those interested in water infrastructure and climate resilience.

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.
