Summary
Built in 1940, this Earth-type dam stands at 17 feet tall and spans a length of 435 feet, with a storage capacity of 50 acre-feet. It serves various purposes, with a primary function classified as 'Other'. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to state jurisdiction, permitting, inspection, and enforcement.
The dam is situated along the TR BUFFALO CR river/stream, under the jurisdiction of the Tulsa District of the US Army Corps of Engineers. Despite its low hazard potential, the risk assessment for Oknoname 059049 indicates a very high risk level, rated at 1. The dam has one valve outlet gate and a controlled spillway with a width of 1 foot. While the condition assessment is currently not rated, the last inspection took place in August 2011 and the inspection frequency is set at 5 years.
Oknoname 059049 poses a significant risk due to its high-risk rating, despite its low hazard potential. With the dam being ungraded in terms of condition assessment, there is a need for regular inspections and possible risk management measures to ensure the safety and integrity of the structure. The dam's location in a rural area underscores the importance of proper maintenance and emergency preparedness in the event of a potential failure, highlighting the critical role of water resource and climate enthusiasts in monitoring and safeguarding our water infrastructure.

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.
