Summary
Built in 1975 by the USDA NRCS, this dam stands at a height of 25 feet and has a storage capacity of 60 acre-feet. With a controlled spillway type and a maximum discharge of 810 cubic feet per second, Bryant No 6 serves a primary purpose of "Other" and is regulated by the OWRB.
Despite being rated as a low hazard potential structure with a very high risk assessment, Bryant No 6 has not been inspected since 2005, with a scheduled inspection frequency of 5 years. The dam features a single valve outlet gate and is constructed of stone core types with soil foundations. While the condition assessment is currently listed as "Not Rated," the risk management measures and emergency response preparedness for this dam are not explicitly documented.
Water resource and climate enthusiasts will find Bryant No 6 to be an intriguing case study in dam infrastructure maintenance and risk assessment. With its unique design and geographical location, this dam presents an opportunity for further exploration into the regulatory oversight and management of private dams in Oklahoma. As efforts are made to address the high risk associated with this structure, stakeholders and policymakers may look towards enhancing inspection protocols and emergency response preparedness to ensure the safety and security of Bryant No 6 and surrounding communities.

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.
