Summary
Completed in 1975, this earth dam stands at 27 feet high with a length of 1290 feet, providing a storage capacity of 544 acre-feet. Situated on TR-BEEF CREEK, this dam plays a crucial role in managing water resources in the area, with a controlled spillway and a valve outlet gate.
Although last inspected in November 2011 and assessed to be in fair condition, the dam is classified as having a significant hazard potential, with a very high risk rating. The dam is managed by the Oklahoma Water Resources Board and falls under state jurisdiction for permitting, inspection, and enforcement. With a history of flood risk reduction and a capacity to handle high discharge rates, the SCS-Maysville Laterals Site-B6 dam is an essential structure in the region's water resource infrastructure.
Despite its age, the dam continues to serve its purpose effectively, mitigating flood risks and ensuring water resource stability for the community of MAYSVILLE. With a dedicated regulatory agency overseeing its operations and maintenance, this dam remains a key asset in the region's water management strategy, demonstrating the importance of sustainable infrastructure for climate resilience and resource conservation.

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.
