Summary
Constructed in 1959, this Earth type dam spans 360 feet in length and reaches a height of 47 feet, with a storage capacity of 270 acre-feet. The dam's primary purpose remains unspecified, adding an air of mystery to its function within the local water system.
Operated under the regulatory oversight of the Oklahoma Water Resources Board, the Lee Oil Company dam boasts a controlled spillway and a single valve outlet gate for water release. Despite its age, the dam's hazard potential is rated as low, making it a low-risk structure in terms of potential failure. However, its condition assessment has not been rated, leaving room for improvement in terms of maintenance and safety measures.
With a risk assessment classifying it as very high, the Lee Oil Company dam calls for close monitoring and potential risk management measures in the future. Its close proximity to the Tri. to Buffalo Creek stream adds to its importance in the local water infrastructure, making it a key player in the region's water resource management efforts. For water resource and climate enthusiasts, the Lee Oil Company dam serves as a fascinating case study of a privately owned structure navigating the complexities of water regulation and management in Oklahoma.

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.
