Summary
is a private water resource located in Stephens, Oklahoma, near Countryside Church. This dam, completed in 1960, serves as a crucial structure for controlling the flow of the TR South Fork Deer Creek. With a height of 20 feet and a hydraulic height of 15 feet, Morgan L.T. has a storage capacity of 53 acre-feet, providing essential water management for the surrounding area.
Managed by the Oklahoma Water Resources Board, Morgan L.T. boasts a low hazard potential and a very high risk assessment rating. Despite its age, this earth dam with stone core continues to meet state regulatory standards, demonstrating its reliability and importance for water resource management in the region. The dam features a controlled spillway and a valve outlet gate, ensuring efficient water release when needed.
Although not extensively modified over the years, Morgan L.T. undergoes regular inspections every five years to assess its condition and ensure its continued safety and functionality. With the potential to discharge up to 693 cubic feet per second and a normal storage capacity of 40 acre-feet, this dam remains a vital asset for water resource enthusiasts and climate advocates in the area.

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.
