Ethel Lake Dam dam
Ethel Lake Dam
Ethel Lake Dam in Macon, Missouri, stands as a vital water resource providing water supply to the community since its completion in 1950. 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
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Ethel Lake Dam
Where does the data for Ethel Lake Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
