Summary
Built in 1972 by Kennoy Engineers Inc., this earth dam stands at a height of 44 feet and stretches 870 feet in length. With a maximum storage capacity of 1144 acre-feet and a surface area of 77 acres, the dam serves as a vital resource for the surrounding community.
Managed by the DAM AND RESERVOIR SAFETY PROG, the Lake Lafayette Dam has a high hazard potential but is currently in satisfactory condition following a recent assessment in 2007. Despite the moderate risk level assigned to this structure, regular inspections are conducted every 3 years to ensure its safety and integrity. With an uncontrolled spillway and valve outlet gates, the dam is equipped to handle a maximum discharge of 2589 cubic feet per second.
As a significant feature along the TR-EAST FORK SNI-A-BAR CREEK, Lake Lafayette Dam not only provides recreational opportunities for locals but also plays a crucial role in water resource management within the region. Its historical significance and environmental impact make it a noteworthy site for water resource and climate enthusiasts to explore and study.

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.
