Summary
Completed in 2002, this dam stands at a height of 27 feet with a hydraulic height of 26 feet and a structural height of 32 feet. It has a length of 353 feet and a maximum storage capacity of 26 acre-feet, serving a drainage area of 168 acres.
Despite being unregulated by the state and having a low hazard potential, Main Trust Dam has a moderate risk assessment rating. The dam features an uncontrolled spillway and outlet gates, with a spillway width of 10 feet. While the dam's condition assessment is not rated, it has not been inspected since its completion in 2002. The risk management measures and emergency action plan for the dam are not clearly defined in the available data.
Main Trust Dam on TR-Sights Branch in Linn County, Missouri, serves as a vital water resource for fire protection and agricultural activities in the region. With its strategic location and purposeful design, this dam plays a significant role in managing water resources and supporting the local ecosystem. For water resource and climate enthusiasts, Main Trust Dam represents a key infrastructure project that highlights the importance of sustainable water management practices in rural communities.

Dam Data Reference
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.
