Summary

Completed in 1953, this earth dam stands at a height of 38 feet and spans 390 feet in length. With a storage capacity of 100 acre-feet and a surface area of 6.4 acres, the dam serves as a crucial structure for water resource management in the area.

Managed by the Kentucky Division of Water, Hanson Oil Company Dam is regulated, inspected, and enforced by state authorities to ensure its safety and functionality. The dam's primary purpose is categorized as 'Other', with low hazard potential and a moderate risk assessment rating. Although not currently rated for its condition, the dam has undergone inspections every 5 years, with the last one conducted in May 2005.

Situated on the TR-East Fork Branch river or stream, Hanson Oil Company Dam plays a significant role in water storage and flood control in the region. With its historical significance dating back to the 1950s, the dam continues to be a vital infrastructure for water resource enthusiasts and climate advocates interested in sustainable management practices.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
