Summary
Constructed in 1965, this dam stands at a height of 30 feet and has a storage capacity of 300 acre-feet. With a surface area of 11 acres, White Connie J serves a primary purpose of "Other," with a low hazard potential and a very high risk assessment rating.
Managed by the Oklahoma Water Resources Board, White Connie J is state regulated and meets all state permitting, inspection, and enforcement requirements. Despite not being federally owned or funded, this dam plays a crucial role in water resource management in the region. With a controlled spillway and one outlet gate, White Connie J is equipped to handle emergency situations, although its emergency action plan and risk management measures are currently not available.
For water resource and climate enthusiasts, White Connie J presents an intriguing case study in dam infrastructure and risk assessment. As a privately owned structure with state jurisdiction, this dam exemplifies the importance of regulatory compliance and emergency preparedness in safeguarding communities and water resources. Its location in Kingfisher County, Oklahoma, and its association with the Tulsa District of the US Army Corps of Engineers make White Connie J a focal point for monitoring and managing water resources in the region.

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.
