Summary
Completed in 1977, this dam stands at a height of 27 feet and has a storage capacity of 361 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," the dam has not been deemed as a significant risk for potential failure.
This structure, managed by the St. Louis District of the US Army Corps of Engineers, plays a crucial role in regulating water flow from the TR to Black Creek. Despite not being state-regulated or inspected, Trenhaile Lake Dam serves as a vital water resource for the surrounding area. Although lacking specific information on spillways or outlet gates, the dam's associated structures and risk management measures are currently unspecified.
For water resource and climate enthusiasts, Trenhaile Lake Dam presents an intriguing case study of a privately owned irrigation dam in Missouri. While it may not be subject to regular state inspections or enforcement, its low hazard potential and consistent water storage capacity demonstrate its importance in maintaining water availability for agriculture in the region. As efforts continue to monitor and manage the dam's condition, it remains a key component in the local water infrastructure.

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.
