Summary
The dam stands at a height of 21 feet with a length of 720 feet, providing a storage capacity of 97 acre-feet and covering a surface area of 10 acres. It is classified as an Earth dam with a stone core foundation, designed to control the flow of the TR-Mussel Fork river.
Despite being privately owned, the Wright Lake Dam is not regulated or inspected by the state of Missouri. With a low hazard potential and a moderate risk assessment rating, the dam has not been rated for its condition or undergone recent inspections. The spillway is uncontrolled with a width of 12 feet, capable of handling a maximum discharge of 43 cubic feet per second. While the dam poses a moderate risk, it serves an essential purpose in providing fire protection, stock water, and stabilizing the grade in the surrounding area.
Although the Wright Lake Dam may not be subject to regular oversight or maintenance measures, its role in supporting fish and wildlife habitats, as well as providing essential water resources for the region, makes it a significant structure for water resource and climate enthusiasts to monitor and advocate for its proper upkeep and management to ensure the safety and sustainability of the surrounding ecosystem.

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.
