Summary
Built in 1940 by the USDA NRCS, this dam on the TR-BUFFALO CR river has a height, hydraulic height, and structural height of 26 feet, with a length of 670 feet. It serves a primary purpose of "Other" and has a storage capacity of 50 acre-feet, with a maximum discharge of 3700 cubic feet per second. The dam features a controlled spillway and a single valve outlet gate.
Despite being classified as having a low hazard potential, Oknoname 059061 is considered to have a very high risk level, with a risk assessment rating of 1. Although the dam's condition is currently not rated, it underwent its last inspection in August 2006, with a scheduled inspection frequency of every 5 years. The dam is regulated by the Oklahoma Water Resources Board and meets state permitting, inspection, and enforcement requirements.
Overall, Oknoname 059061 represents an important water resource structure in Oklahoma, providing essential flood control and water storage capabilities. With its historical significance and continued regulatory oversight, this dam serves as a vital component of the state's water management infrastructure, ensuring the safety and protection of surrounding communities and ecosystems in the face of changing climate conditions.

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.
