Summary
The dam, classified as an earth dam with a buttress core type, stands at a height of 25 feet and has a storage capacity of 67 acre-feet. With a surface area of 5 acres and a drainage area of 280 acres, the dam plays a crucial role in managing water resources in the region.
Despite being privately owned, Maxson Lake Dam is not regulated or permitted by the state of Missouri. The dam is considered to have low hazard potential and is not currently rated for its condition. While it does not have an emergency action plan in place, the dam continues to provide essential functions for the community, including recreation opportunities. The dam's location on TR-Walnut Creek contributes to its significance in the local ecosystem.
Water resource and climate enthusiasts can appreciate Maxson Lake Dam for its historical significance and its role in water management in Johnson County, Missouri. The dam's construction in the early 1950s reflects a time when infrastructure development played a vital role in supporting agricultural and recreational activities in the region. As climate change continues to impact water resources, understanding the importance of dams like Maxson Lake Dam becomes increasingly crucial for sustainable water management practices in the future.

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.
