Summary
is a private earth dam located in Fairview, Oklahoma, along the TR-Barney Creek. Built in 1941, this dam stands at a height of 30 feet with a length of 312 feet, providing a storage capacity of 240 acre-feet. Despite its low hazard potential, Clark J. is deemed to have a very high risk due to its age and condition assessment being not rated.
Managed by the Oklahoma Water Resources Board, Clark J. has state jurisdiction and regulatory oversight, with permitting, inspection, and enforcement mechanisms in place. The dam features a controlled spillway and a single valve outlet gate, ensuring controlled water discharge and management. Although last inspected in 2009, with a scheduled inspection frequency of 5 years, the dam's emergency action plan and risk assessment are areas that require attention and potentially updating.
For water resource and climate enthusiasts, Clark J. presents an intriguing case study of a historic earth dam in Oklahoma with a unique mix of design elements and risk factors. As a key component of the local water infrastructure, understanding the maintenance and management challenges faced by dams like Clark J. is crucial for ensuring the safety and sustainability of water resources in the region. Further research and monitoring efforts may be needed to address the identified risks and enhance the resilience of this important water structure.

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.
