Summary
As a privately owned structure, the dam stands at a height of 20 feet and has a storage capacity of 255 acre-feet, providing a surface area of 18 acres for water enthusiasts to enjoy. Despite its primary purpose for recreation, the dam also presents a high hazard potential, although its condition assessment has not been rated.
While the dam has not been regulated or inspected by state authorities, its ownership and maintenance fall under private jurisdiction. The Kansas City District oversees the USACE operations, although there is no federal agency funding or involvement in the structure's design or construction. The dam's emergency action plan, condition assessment, and risk management measures have not been fully assessed or implemented, raising concerns about its safety and preparedness in the event of a disaster.
With its picturesque location and potential for recreational use, Trojan Lake Dam serves as a valuable water resource in the region. However, its lack of regulatory oversight and maintenance updates highlight the importance of ensuring the safety and structural integrity of the dam to protect both the environment and public safety in the area.

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.
