Summary
This dam stands at a height of 31 feet with a hydraulic height of 27 feet and a length of 1470 feet, providing a storage capacity of 1096 acre-feet. The dam's spillway is of the controlled type with a width of 1 foot, ensuring effective water flow management during high discharge events.
The dam's hazard potential is rated as low, with a very high risk assessment score of 1. Despite being constructed in 1976, the last inspection was conducted in 1980, with an inspection frequency of 5 years. The condition assessment is currently not rated, highlighting the need for further evaluation to ensure the dam's structural integrity and continued effectiveness in flood risk reduction. Additionally, emergency preparedness measures such as the existence of an emergency action plan and updated contact information are not specified, posing potential risks in emergency situations.
Water resource and climate enthusiasts can appreciate the significance of SCS-Upper Bayou Site-08 in mitigating flood risks in Carter County, Oklahoma. The dam's design and construction by the Natural Resources Conservation Service reflect a commitment to sustainable water management practices. However, the lack of recent inspections and condition assessments underscore the importance of regular maintenance and monitoring to ensure the dam's continued functionality and safety in the face of changing climate conditions and increasing water-related risks.

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.
