Summary
Constructed in 1969 by the Soil Conservation Service, USDA NRCS, this earth dam stands at a height of 38 feet and spans 2230 feet in length. With a normal storage capacity of 427 acre-feet and a maximum storage of 7208 acre-feet, this dam plays a crucial role in managing water flow and mitigating flood risks in the East Fork Clarks River watershed. The dam is regulated by the KY Division of Water and undergoes regular inspections to ensure its structural integrity.
Despite being assessed as in fair condition during its last inspection in January 2018, East Fork Clarks River FRS 28a is classified with a significant hazard potential, highlighting the importance of ongoing maintenance and risk management measures. The dam's spillway, which is uncontrolled and 60 feet wide, is designed to handle excess water flow during periods of high discharge. The surrounding area covers 96 acres, serving a drainage area of 15.5 square miles. With a moderate risk assessment rating of 3, the dam is closely monitored to prevent any potential emergencies and ensure the safety of nearby communities.
Managed by the Natural Resources Conservation Service, East Fork Clarks River FRS 28a is a key component in the water resource infrastructure of Marshall County, Kentucky. Its strategic location and design contribute to the overall flood risk reduction efforts in the region, providing essential protection to residents and property along the East Fork Clarks River. As climate change continues to impact water resources, structures like this dam play a crucial role in safeguarding communities and ecosystems against the threats of flooding and water-related disasters.

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.
