Summary
Built in 1955, this earthen dam stands at a height of 22 feet and has a storage capacity of 80 acre-feet. The dam serves various purposes and is regulated by the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
Located in the Tulsa District, Johnson Land & Cattle Co dam has a controlled spillway and a low hazard potential. Despite not being condition rated, the dam is regularly inspected every five years, with the last inspection conducted in July 2005. The risk assessment for the dam is very high (1), indicating the need for proper risk management measures and potentially heightened monitoring in the future to ensure the safety of the surrounding area and water resources.
Overall, Johnson Land & Cattle Co dam plays a crucial role in managing water resources in the region, with its structure and operations meeting state regulatory standards. As a significant feature in the landscape, it highlights the intersection of private ownership, environmental stewardship, and the need for consistent monitoring and maintenance to mitigate risks associated with high hazard potential and the potential impacts on the surrounding community and ecosystem.

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.
