Summary

Completed in 1940, this dam serves a primary purpose of "Other" and has a normal storage capacity of 50 acre-feet. It is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with the last one conducted in December 2010.

Despite being classified as having a low hazard potential, Oknoname 103001 is considered to have a very high risk due to its location on the TR-Little Stillwater Creek. The dam features a controlled spillway with a width of 1 foot and one valve outlet gate. The risk assessment for this structure is rated as "Very High (1)", indicating the need for thorough risk management measures to ensure the safety of nearby communities and water resources.

Overall, Oknoname 103001 represents an important component of Oklahoma's water infrastructure, with a focus on regulatory compliance, regular maintenance, and risk assessment. The dam's role in water management and flood control underscores the importance of monitoring and maintaining such structures in the face of changing climate patterns and increasing water resource challenges.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
