Summary

Built in 1953, this earth dam stands at a height of 50 feet and has a length of 670 feet, creating a reservoir with a maximum storage capacity of 3640 acre-feet. With a normal storage capacity of 2189 acre-feet, the dam serves not only for water supply but also for recreational purposes, covering a surface area of 150 acres.

Managed by the Kentucky Division of Water, the dam is subject to regular inspections to ensure its structural integrity and safety. The hazard potential of the dam is classified as high, but its condition assessment is rated as satisfactory. In 2021, the dam underwent hydraulic modifications to enhance its performance and resilience. Despite being a risk management concern with a moderate risk assessment rating of 3, the dam remains a critical infrastructure asset for water resource management in Grant County, Kentucky.

With the Bulluck Pen Creek as its primary source, the Bullock Pen Lake Dam provides essential water resources for the community while offering recreational opportunities for residents and visitors alike. Its uncontrolled spillway, with a width of 260 feet, allows for controlled discharge during periods of excess water flow. As climate change continues to impact water resources, the management and maintenance of structures like Bullock Pen Lake Dam are essential for ensuring water security and resilience in the face of evolving environmental challenges.

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.
