Summary

Built in 1960, the Earth dam stands at 27 feet high and stretches 860 feet in length, with a storage capacity of 125 acre-feet. The dam's primary purpose is categorized as "Other," and it is regulated by the Oklahoma Water Resources Board.

Despite its low hazard potential, Carter No 1 is classified as having a very high risk due to its condition assessment being labeled as "Not Rated." The dam has a controlled spillway with a width of 1 foot and features a single valve outlet gate. The last inspection date recorded was in 1997, with an inspection frequency of 5 years, highlighting the importance of regular maintenance and monitoring for this structure.

Water resource and climate enthusiasts interested in the intricacies of dam infrastructure will find Carter No 1 a fascinating case study. Its location in Carter County, Oklahoma, and its association with the Fort Worth District highlight the importance of proper regulation and inspection protocols to ensure the safety and functionality of such structures in the face of changing climate conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
