Summary
Built in 1976 by the USDA NRCS, this dam on TR-Canton Lake stands at a height of 28 feet and has a maximum storage capacity of 60 acre-feet. It serves a primary purpose of "Other" and is regulated by the Oklahoma Water Resources Board (OWRB) with state jurisdiction and permitting in place.
With a low hazard potential and a very high risk assessment rating, Jantzen No 2 is equipped with a controlled spillway and a single valve outlet gate for water management. The dam has not been rated in terms of condition assessment, but it undergoes inspections every five years to ensure its structural integrity. While the risk management measures and emergency action plan status are not specified, the dam's risk assessment indicates a need for vigilance and preparedness in the face of potential hazards.
For water resource and climate enthusiasts, Jantzen No 2 presents an intriguing case study of a privately owned dam in a rural area, highlighting the importance of regulatory oversight and risk management in safeguarding water infrastructure. The dam's location on TR-Canton Lake, its design by the USDA NRCS, and its association with the Tulsa District of the US Army Corps of Engineers underscore the interconnectedness of various agencies in ensuring the safety and functionality of water resources. As climate change impacts water systems, understanding the maintenance and monitoring of structures like Jantzen No 2 is crucial for sustaining water availability and mitigating risks in the face of evolving 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.
