Summary
This earth dam, with a buttress core type, stands at a height of 25 feet and has a storage capacity of 94 acre-feet. Although it currently has a low hazard potential and is not rated for its condition, its significance lies in its role within the Wm Logan State Wildlife Area and its contribution to the management of the local ecosystem.
Situated on TR-DRY BR MILL CREEK, this dam plays a crucial role in regulating the water levels in the area, with a normal storage capacity of 58 acre-feet and a surface area of 7 acres. Despite its modest size, the dam's impact on the surrounding environment cannot be understated. With no state regulation or jurisdiction, and minimal inspection and enforcement measures in place, it operates under the primary ownership of the state of Missouri and holds a key position within the Kansas City District of the US Army Corps of Engineers.
As water resource and climate enthusiasts explore the intricacies of Wm Logan State Wildlife Area Lk#4 Dam, they will uncover a unique blend of ecological and structural significance. With its unlisted foundation type and limited historical data on completion and modifications, this dam stands as a testament to the delicate balance between human intervention and natural systems. As efforts to assess and manage the risks associated with dams continue to evolve, this structure serves as a reminder of the complex interactions between water resources, wildlife habitats, and human infrastructure in the heart of Missouri's diverse landscape.

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.
