Summary
Built in 1978, this earth dam stands at a height of 24 feet and serves as a crucial structure for water resource management in the area. With a storage capacity of 110 acre-feet and a maximum discharge of 800 cubic feet per second, Morgan Gr plays a vital role in flood control and water supply for the surrounding community.
Despite being classified as having a low hazard potential, Morgan Gr is considered to have a very high risk due to its condition assessment not being rated and its emergency action plan status being unclear. The dam features a controlled spillway and a single valve outlet gate, indicating a level of sophistication in its design. The risk management measures and overall risk assessment for Morgan Gr are currently not detailed, raising concerns for potential vulnerabilities in the face of climate variability and extreme weather events.
As water resource and climate enthusiasts, it is essential to monitor the maintenance and inspection of dams like Morgan Gr to ensure their continued functionality and safety. With its proximity to the TR-CANEY BOGGY CR river and its importance in water management for Hughes County, Oklahoma, Morgan Gr serves as a critical infrastructure that requires diligent oversight and risk management strategies to withstand the challenges of a changing climate.

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.
