Summary
Standing at a height of 18 feet, this dam serves multiple purposes, with a primary purpose classified as 'Other'. The dam's main components include a stone core and a soil foundation, with a controlled spillway and one valve outlet gate for water release. The dam has a storage capacity of 70 acre-feet, with a maximum discharge rate of 180 cubic feet per second.
Despite being rated as having a low hazard potential, Oknoname 049023 is considered to have a very high risk due to its location and characteristics. It falls under the jurisdiction of the Oklahoma Water Resources Board (OWRB), and is subject to state regulations, permitting, inspection, and enforcement. The dam has not been rated for its condition assessment, and its emergency action plan status and risk management measures are unknown. The last inspection of the dam was conducted in February 2002, with an inspection frequency of every 5 years.
With a notable history and a unique design, Oknoname 049023 presents an interesting case study for water resource and climate enthusiasts. Its location in Garvin County, Oklahoma, and its association with Rush Creek make it a significant water resource structure in the region. The dam's characteristics and risk profile provide valuable insights into the management and assessment of similar earth dams in the state. Further research and analysis of Oknoname 049023 could contribute to a better understanding of dam safety and climate resilience in the face of changing environmental conditions.

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.
