Summary
This gravity dam was completed in 1932 and stands at a height of 30 feet, with a hydraulic height of 27 feet. It serves as a crucial structure for managing water flow along TR-MILL CR, with a maximum storage capacity of 248 acre-feet.
Despite its age, Coblentz remains in good condition with a low hazard potential. The dam is inspected every 5 years to ensure its structural integrity and safety. The risk assessment for Coblentz indicates a very high level of risk, highlighting the importance of continued monitoring and maintenance efforts to mitigate any potential dangers associated with its operation.
Located in Lewisville C., Coblentz plays a vital role in water management in the region, with a controlled spillway and one valve outlet gate. The dam's primary purpose is listed as "Other," reflecting its versatile use for various water resource management activities. With state regulation and oversight from the Oklahoma Water Resources Board, Coblentz serves as a key infrastructure for water supply and flood control in the area, making it a significant asset for water resource and climate enthusiasts to keep an eye on.

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.
