Summary

Owned privately, this earth dam stands at a height of 30 feet and has a storage capacity of 128 acre-feet. Despite its low hazard potential, the condition assessment of Laschke Lake Dam is currently not rated.

Situated on the TR to Pin Oak Creek, this dam in Franklin County, Missouri, covers a surface area of 8 acres with a drainage area of 60 acres. Managed by the St. Louis District of the US Army Corps of Engineers, Laschke Lake Dam has not been subject to state regulation, inspection, or enforcement. While the dam's spillway width and outlet gates are unspecified, its primary purpose and design as an earth dam with buttress core types reflect its functionality for both water resource management and recreational activities.

Laschke Lake Dam represents a key water resource structure in the region, providing essential services for both local fire protection and recreational activities. With a history dating back to the 1960s, this dam continues to contribute to the landscape of Franklin County, Missouri, while maintaining a low hazard potential. As water resource and climate enthusiasts, the multifaceted role of Laschke Lake Dam in sustaining both natural ecosystems and human activities makes it a significant focal point for further study and appreciation.

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.
