Summary
Completed in 1978, this dam stands at a height of 25 feet with a maximum storage capacity of 50 acre-feet. It is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with the last inspection conducted in December 2010. Despite being classified as having a low hazard potential, the risk assessment for Bolay Bob is rated as very high.
Situated on TR Black Bear Creek within the Tulsa District, Bolay Bob features a controlled spillway with a width of 1 foot and a single valve outlet gate. The dam is surrounded by a surface area of 1 acre and serves as a vital infrastructure for managing floodwaters in the region. While the dam's condition assessment is currently not rated, its risk management measures and emergency action plan status remain unreported. With its strategic location and crucial role in flood risk reduction, Bolay Bob stands as a significant water resource structure in Oklahoma.
Owned by a private entity, Bolay Bob contributes to the overall flood resilience of the region, providing essential protection against potential inundation. With its stone core and soil foundation, the dam has been designed to withstand hydraulic pressures and manage water flow effectively. The dam's location in a high-risk area underscores the importance of regular inspections and adherence to regulatory guidelines to ensure the safety and functionality of this critical water resource infrastructure for the community.

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.
