Summary
Situated on TR-ROWLAND CREEK, this earth-type dam stands at 28 feet tall and spans 260 feet in length, with a storage capacity of 50 acre-feet. Managed by the Oklahoma Water Resources Board, Bethel Bill is subject to state regulations, permitting, inspections, and enforcement to ensure its structural integrity and safety.
Despite its low hazard potential, Bethel Bill faces a very high risk assessment due to its age and limited maintenance and management measures. Although the dam is currently in a not-rated condition, it is crucial for stakeholders to address potential risks and implement necessary risk management strategies to safeguard the surrounding community and environment. The dam's controlled spillway and single valve outlet gate contribute to its operational functionality, while its location in the Tulsa District adds to its significance within the region.
With its historical significance and recreational value, Bethel Bill serves as a valuable water resource for the local community while also posing potential risks that require proactive management and oversight. As climate change impacts water resources and infrastructure resilience, ongoing monitoring and maintenance of dams like Bethel Bill are essential to ensure their continued safety and sustainability for future generations of water resource and climate enthusiasts.

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.
