Summary

Completed in 1965, the primary purpose of this Earth dam is flood risk reduction, with a height of 21 feet and a length of 400 feet. It has a storage capacity of 100 acre-feet and a surface area of 7 acres, serving the surrounding area in Canadian County.

Despite being classified as low hazard potential and not currently rated for condition assessment, Brown-McClure poses a very high risk, as indicated by its risk assessment score of 1. The dam has been inspected infrequently, with the last inspection conducted in August 2010. While it has a controlled spillway and a single valve outlet gate, there are no associated locks or modifications. The dam's emergency action plan (EAP) status, as well as its inundation maps and risk management measures, are not specified in the available data.

For water resource and climate enthusiasts, Brown-McClure presents an intriguing case study of a privately owned dam in Oklahoma with flood risk reduction as its primary purpose. The data highlights the importance of regular inspections and risk assessments for such infrastructure, especially given the high risk associated with this particular dam. Understanding the intricacies of dam management and emergency preparedness is crucial for ensuring the safety and resilience of communities that rely on these structures for flood control and water management.

Dam Data Reference

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.
