Summary
is a privately owned earth dam located in Meridian, Oklahoma, along Blue Creek. Completed in 1965, this structure stands at 30 feet in height and spans 600 feet in length, with a storage capacity of 230 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections and enforcement activities to ensure its safety and compliance with state regulations.
Despite its low hazard potential, Tenny H.E. has been designated as having a very high risk due to its age and condition assessment not being rated. With a controlled spillway and one outlet valve, this dam is equipped to manage a maximum discharge of 1700 cubic feet per second. While the emergency action plan and risk management measures for Tenny H.E. are currently not fully detailed, its location in Logan County, Oklahoma, highlights the importance of monitoring and maintaining water resources in the face of changing climate patterns.
For water resource and climate enthusiasts, Tenny H.E. provides a fascinating case study in dam infrastructure management and risk assessment. As a privately owned structure in a region vulnerable to extreme weather events, understanding the maintenance and regulatory processes for dams like Tenny H.E. is crucial for ensuring the safety and sustainability of our water resources. The data on Tenny H.E. serves as a reminder of the intricate interplay between human-made structures and natural forces, highlighting the ongoing challenges and opportunities in water resource management in a changing climate.

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.
