Summary
Completed in 1994, the dam serves primarily for irrigation purposes, with a storage capacity of 102 acre-feet. The dam stands at a height of 29 feet and has a controlled spillway type with a width of 1 foot.
The dam is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to state inspection, permitting, and enforcement. Despite being classified as a low hazard potential structure, the risk assessment for Jack Clark #1 is rated as very high (1), indicating the need for comprehensive risk management measures. The last inspection of the dam was conducted in August 2011, with an inspection frequency of every 5 years.
Located in Logan County, Oklahoma, Jack Clark #1 is a crucial component of the local water resource infrastructure, contributing to the irrigation needs of the surrounding area. As a key asset for water management in the region, maintaining the structural integrity and safety of the dam is essential to ensure the continued availability of water for agricultural purposes. With its strategic location and importance for water resource management, Jack Clark #1 represents a vital piece of the state's infrastructure that requires careful monitoring and maintenance to mitigate potential risks and ensure long-term sustainability.

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.
