Summary

Built in 1960, this Earth-type dam stands at a height of 20 feet and spans a length of 1000 feet, with a storage capacity of 200 acre-feet. The primary purpose of this dam is water supply, serving as a crucial resource for the local community in the area.

Managed by the OWRB, Brooks Wiley H has been deemed to have a low hazard potential but a very high risk assessment, ranking at 1. Despite its condition not being rated, it undergoes regular inspections every five years, with the last one conducted in November 2002. Equipped with a controlled spillway and a single valve outlet gate, this dam plays a vital role in maintaining water security and management in the region.

With its strategic location and essential function in water supply, Brooks Wiley H stands as a significant water resource infrastructure in McIntosh, Oklahoma. Its presence along TR-Chouteau Creek not only ensures water availability but also highlights the importance of proper dam management and safety measures in mitigating potential risks and safeguarding the surrounding community and environment.

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.
