Summary

The privately owned earth dam boasts a height of 32 feet and a storage capacity of 68 acre-feet, making it an essential water resource for the surrounding area. Situated along the TR to Joachim Creek, the dam offers not only recreational opportunities but also serves as a critical component of the local ecosystem.

Despite its high hazard potential, Little Lake Dam has not been rated for its condition assessment as of the last inspection in 1981. With its primary purpose being recreation, the dam provides a serene environment for outdoor enthusiasts to enjoy fishing, boating, and wildlife observation. The dam's location in DeSoto, Missouri, adds to its allure as a popular destination for water resource and climate enthusiasts looking to explore the beauty of the region.

As a well-known landmark in the Kansas City District, Little Lake Dam holds historical significance and continues to play a vital role in the local community. While its condition assessment remains unrated, the dam's enduring presence underscores the importance of water resource management and the need for regular inspections and maintenance to ensure its long-term sustainability. For those passionate about water resources and climate, Little Lake Dam offers a glimpse into the intersection of human engineering and environmental stewardship.

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.
