Summary
Constructed in 1994 for irrigation purposes, this dam stands at a height of 30 feet and has a storage capacity of 368 acre-feet. With a drainage area of 900 acres and a maximum discharge of 270 cubic feet per second, this dam plays a crucial role in water management in the region.
Managed by the Oklahoma Water Resources Board, Jack Clark #2 has a low hazard potential and has not been rated for condition assessment. Despite its low hazard potential, the dam is considered to have a very high risk due to its location and structural characteristics. The dam is equipped with a controlled spillway and a single valve outlet gate for water release. While the dam has not been modified in recent years, it undergoes inspections every five years to ensure its safety and functionality.
Jack Clark #2 serves as a vital infrastructure for irrigation and water resource management in Logan County, Oklahoma. With its strategic location and storage capacity, this earth dam plays a crucial role in regulating water flow and supporting agricultural activities in the area. As climate change continues to impact water resources, the maintenance and monitoring of dams like Jack Clark #2 will be essential to ensure the resilience of the region's water supply in the face of changing environmental conditions.

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.
