Summary
This dam, completed in 1955, stands at a height of 15 feet and has a storage capacity of 120 acre-feet. It serves as a critical structure for flood control and water storage on Rainy Mountain Creek, with a controlled spillway and a maximum discharge capacity of 1380 cubic feet per second.
Despite being rated as having low hazard potential, Oknoname 075011 poses a very high risk due to its structural characteristics and location. The dam has not been rated for its condition, and the last inspection was conducted in November 2001, with an inspection frequency of every 5 years. The dam's emergency action plan status, risk management measures, and inundation maps are not available, raising concerns about its preparedness for emergencies and potential risks to downstream communities.
With a lack of information on crucial aspects like condition assessment, emergency preparedness, and risk management, Oknoname 075011 presents a concerning case for water resource and climate enthusiasts. As a privately owned dam regulated by the Oklahoma Water Resources Board, it warrants further attention and monitoring to ensure its safety and functionality for the surrounding area.

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.
