Summary
This flood risk reduction structure spans 1110 feet along TR-BEEF CREEK, with a height of 29 feet and a storage capacity of 284 acre-feet. The dam's spillway is controlled, with a maximum discharge of 980 cubic feet per second, serving a drainage area of 0.77 square miles. Despite its fair condition assessment and high hazard potential, the dam's risk assessment is deemed very high, indicating the need for proactive risk management measures.
Managed by the Oklahoma Water Resources Board, SCS-Maysville Laterals Site-B3 is critical for flood risk reduction in the region, particularly along TR-BEEF CREEK. With a surface area of 12 acres and a normal storage capacity of 40 acre-feet, the dam plays a crucial role in mitigating flood impacts and protecting downstream communities. The dam's structural integrity and overall condition are closely monitored, with inspections conducted at a frequency of once per year to ensure compliance with state regulatory standards and enforcement measures.
As part of the Tulsa District's infrastructure portfolio, SCS-Maysville Laterals Site-B3 poses significant risks due to its high hazard potential and very high risk assessment rating. The dam's location in a high-risk area necessitates the development of comprehensive risk management strategies to address potential failures and ensure the safety of surrounding communities. With a history of state oversight and regulatory compliance, this flood risk reduction structure remains a key feature in Oklahoma's water resource and climate resilience efforts.

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.
