Summary

The earth dam stands at a height of 23.4 feet with a hydraulic height of 20.3 feet, creating a reservoir with a storage capacity of 94.9 acre-feet. The dam has a low hazard potential and a moderate risk assessment score of 3, with no recent condition assessment available.

Managed by a private owner, Lassetter Lake Dam is not regulated or inspected by the state authorities. The dam features an uncontrolled spillway and outlet gates, with no associated locks. Despite its age, the dam has not undergone any significant modifications or inspections since 1985. It is situated in a serene location, offering a surface area of 7.4 acres for outdoor enthusiasts to enjoy various water activities.

Although Lassetter Lake Dam may not be on the radar of federal agencies or state regulators, its presence provides a valuable recreational resource for the local community. With its uncontrolled spillway and moderate risk assessment, the dam serves as a reminder of the importance of maintaining and monitoring water infrastructure to ensure the safety and enjoyment of all who visit.

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.
