Summary
Constructed in 1977, this dam stands at a height of 18 feet and has a maximum storage capacity of 90 acre-feet. With a primary purpose categorized as "Other," Jarvis C serves various functions beyond flood control, showcasing its versatility in water resource management.
Managed by the Oklahoma Water Resources Board, Jarvis C is regulated, permitted, inspected, and enforced by the state agency, ensuring its structural integrity and safety. Despite being classified as having a low hazard potential, the risk assessment for this dam is very high, indicating the importance of ongoing monitoring and risk management measures. With a controlled spillway and one valve outlet gate, Jarvis C is equipped to handle a maximum discharge of 1860 cubic feet per second in case of emergencies.
For water resource and climate enthusiasts, Jarvis C presents an intriguing case study of a privately owned dam with significant storage capacity and a complex risk profile. Its location along the Canadian River and its association with the Tulsa District of the US Army Corps of Engineers add further layers of interest to its management and operational practices. As the dam continues to play a crucial role in water management in Oklahoma, it underscores the need for sustainable and resilient infrastructure in the face of changing climate patterns.

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.
