Summary
Built in 1963 by the USDA NRCS, this structure stands at a height of 25 feet and has a length of 341 feet, with a storage capacity of 53 acre-feet. It serves the primary purpose of water resource management on Buffalo Creek, with a drainage area of 0.81 square miles.
Despite being classified as having a low hazard potential and not currently rated for condition assessment, Catlin #11 presents a moderate risk level (3) according to data analysis. The uncontrolled spillway with a width of 60 feet and the lack of outlet gates raise concerns about its emergency management measures. With no recent inspection data available, it is crucial for stakeholders to prioritize risk assessment and implement necessary risk management measures to ensure the safety and efficiency of this water resource infrastructure.
Enthusiasts of water resources and climate in the region should take note of Catlin #11 as a key earth dam structure on Buffalo Creek. Its historical significance, design specifications, and operational details provide valuable insights into the management of water resources in Oklahoma. Continued monitoring and evaluation of this dam are essential to mitigate risks and maintain its functionality for the surrounding community and ecosystem.

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.
