Summary
Built in 1960, this structure on TR-Rush Creek stands at a height of 18 feet and has a storage capacity of 90 acre-feet. With a controlled spillway and a maximum discharge of 962 cubic feet per second, this dam serves a primary purpose classified as "Other."
Despite being classified as having a low hazard potential, Oknoname 049013 is considered to have a very high risk level, with a risk assessment rating of 1. The dam has not been rated for its condition, and its last inspection was conducted in April 2010. Although the dam meets state regulatory requirements for permitting, inspection, and enforcement, there is no Emergency Action Plan (EAP) in place, and the risk management measures are not specified.
Water resource and climate enthusiasts may find Oknoname 049013 to be an intriguing structure to study due to its location, design characteristics, and risk assessment. Further research into the dam's history, construction, and current condition could provide valuable insights into the management and maintenance of similar earth dams in the region.

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.
