Summary
Completed in 1972, this dam stands at a height of 26 feet with a hydraulic height of 21 feet and a structural height of 26 feet. It has a length of 415 feet and a maximum storage capacity of 50 acre-feet, with a normal storage capacity of 30 acre-feet.
The dam is regulated by the Oklahoma Water Resources Board (OWRB) and is permitted, inspected, and enforced by the state. It serves as a crucial structure for managing water resources in the area, particularly for the TR-Grape Creek. Despite being rated as having a low hazard potential, the risk assessment for Carter Floyd indicates a very high risk level, emphasizing the importance of careful monitoring and maintenance to ensure the safety and integrity of the dam.
With a controlled spillway type and one valve outlet gate, Carter Floyd plays a vital role in flood control and water management in the region. While it has not been rated for its condition assessment, the dam is subject to regular inspections every 5 years to assess its structural integrity and address any potential risks. As a key component in the water infrastructure of Harmon County, the conservation and proper management of Carter Floyd are essential for safeguarding the surrounding area from potential flooding and ensuring a sustainable water supply for the community.

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.
