Summary
Land & Cattle Co. is a privately owned dam that serves multiple purposes, including flood control and irrigation. Built in 1940, this earth dam stands at a height of 30 feet and has a storage capacity of 225 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections and enforcement to ensure its safety and functionality.
The dam's primary purpose is classified as "Other", and it is equipped with a controlled spillway and a single valve outlet gate. With a low hazard potential and a very high risk assessment rating, the Okla. Land & Cattle Co. dam is considered to be in good condition, although it has not been rated formally. In the event of an emergency, the dam has emergency action plans in place, and it is inspected every five years to mitigate any potential risks and ensure public safety.
Overall, the Okla. Land & Cattle Co. dam plays a crucial role in managing water resources in Osage County, Oklahoma. With its strategic location on TR-Antelope Creek and its ability to store and regulate water flow, this dam is a key piece of infrastructure in the region. As water resource and climate enthusiasts, it is important to monitor and support the maintenance and operation of dams like Okla. Land & Cattle Co. to safeguard our water supply and protect against potential environmental risks.

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.
