Summary
Built in 1971, this dam stands at 16 feet in height and has a length of 400 feet, with a storage capacity of 80 acre-feet. Despite its low hazard potential, Carr Margaret is classified as having a very high risk due to its location and potential impact on the surrounding area in the event of a failure.
The dam's primary purpose is listed as "Other," and it is regulated by the Oklahoma Water Resources Board (OWRB). Although it is not federally owned or funded, the dam is subject to state permitting, inspection, and enforcement. The last inspection of Carr Margaret took place in December 2010, and it has an inspection frequency of 5 years.
With its controlled spillway and valve outlet gates, Carr Margaret is designed to manage a maximum discharge of 1600 cubic feet per second. Despite not being rated for its current condition, the dam's risk assessment indicates a very high level of risk, prompting the need for effective risk management measures to ensure the safety of the surrounding community and environment. For water resource and climate enthusiasts, Carr Margaret serves as an important case study in the management of aging infrastructure and the mitigation of potential hazards associated with dam structures.

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.
