Summary
The dam, primarily owned by a private entity, has a height of 53 feet and a length of 1100 feet, with a maximum storage capacity of 258 acre-feet and a normal storage of 230 acre-feet. Situated on TR Little Turkey Creek, the dam serves as a crucial infrastructure for managing water resources in the region.
With a high hazard potential and a satisfactory condition assessment, Ethel Lake Dam is regulated by the DAM AND RESERVOIR SAFETY PROG in Missouri. The dam has a spillway type of 'Uncontrolled' and an inspection frequency of 3 years to ensure its structural integrity and safety. Despite its moderate risk level, the dam plays a crucial role in water management and supply for the New Cambria community, highlighting the importance of sustainable infrastructure for water resource enthusiasts and climate advocates alike.
As one of the key structures in the area, Ethel Lake Dam not only provides essential water supply but also contributes to the overall water management and flood control efforts in Macon County. With its stone core and soil foundation, the dam showcases the blend of engineering and natural elements in creating a sustainable water infrastructure. Its location on TR Little Turkey Creek underscores the significance of such structures in safeguarding water resources and mitigating potential risks associated with high hazard dams.

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.
