Summary
Built in 1966, this earth dam stands at a height of 16 feet with a length of 900 feet, providing a storage capacity of 60 acre-feet and covering a surface area of 3 acres. Despite being unregulated by the state and having a low hazard potential, the dam is classified as having a moderate risk due to its condition assessment not being rated.
The dam features an uncontrolled spillway with a width of 40 feet and a maximum discharge capacity of 135 cubic feet per second. With a drainage area of 190 square miles, Townley Lake Dam serves the local community by providing water for irrigation and recreation. While it has not been inspected recently and lacks an emergency action plan, the dam continues to play a vital role in water resource management in the area.
Although Townley Lake Dam is privately owned and not under the jurisdiction of a state agency, it remains an essential piece of infrastructure for water management in Dade County, Missouri. With its historical significance dating back to the mid-20th century, the dam serves as a reminder of the importance of maintaining and monitoring dams to ensure the safety and sustainability of water resources in the region.

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.
