Summary
Built in 1970, this earth dam stands at a height of 23 feet and has a length of 700 feet. With a maximum storage capacity of 101 acre-feet and a normal storage capacity of 53 acre-feet, this dam serves a primary purpose of "Other" and has a low hazard potential.
Operated by the Oklahoma Water Resources Board, Morgan Carol J is regularly inspected and maintained to ensure its structural integrity. Despite being rated as "Not Rated" in terms of condition assessment, the dam is equipped with a controlled spillway and a single valve outlet gate. In case of emergencies, the dam has emergency action plans in place, although details on their preparation and revisions are currently unavailable.
Although deemed to have a low hazard potential, Morgan Carol J has a very high risk assessment rating of 1. Situated in a region prone to climatic variability and extreme weather events, this dam plays a crucial role in managing water resources and mitigating potential flood risks along TR-Little Sandy Creek. As a noteworthy structure in the Tulsa District, Morgan Carol J serves as a vital component of the local water infrastructure, highlighting the importance of sustainable water resource management in the face of changing climatic conditions.

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.
