Summary
Owned by the local government and regulated by the KY Division of Water, this earth dam on the South Fork Grassy Creek boasts a height of 40 feet and a length of 300 feet. With a storage capacity of 240 acre-feet and a surface area of 10.2 acres, it plays a crucial role in meeting the water needs of the community.
Despite being classified as having a significant hazard potential and fair condition assessment, the Williamstown Reservoir Dam continues to serve as a reliable water resource for the area. With a spillway width of 25 feet and a drainage area of 0.33 square miles, the dam ensures controlled water release during periods of excess inflow. Its location in Grant County, Kentucky, under the jurisdiction of the state regulatory agency, highlights its importance in maintaining water quality and supply for the residents of Williamstown.
For water resource and climate enthusiasts, the Williamstown Reservoir Dam offers a fascinating insight into the intersection of infrastructure and environmental stewardship. From its historical construction by Howard K. Bell and Assoc. to its ongoing inspections and risk assessments, this dam exemplifies the critical role that such structures play in ensuring water security and resilience in the face of changing climate conditions. As a key component of the local water supply system, the dam serves as a testament to the importance of sustainable water management practices in safeguarding our communities for the future.

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.
