Lake Marie Dam dam
Lake Marie Dam
Lake Marie Dam, located in Mercer, Missouri, is a privately owned structure that serves as a vital recreational resource for the area. Completed in 1981, this dam stands at a height of 50 feet and has a length of 1100 feet, creating a reservoir with a normal storage capacity of 882 acre-feet. The dam also plays a crucial role in flood control, with a maximum discharge capacity of 3512 cubic feet per second.
Despite its satisfactory condition assessment in 2007, Lake Marie Dam has been classified as having a high hazard potential. However, the risk assessment remains moderate, indicating a level of preparedness for potential emergencies. The dam is regulated, inspected, and enforced by the Dam and Reservoir Safety Program in Missouri, ensuring compliance with state guidelines and safety measures. With its scenic surroundings and recreational opportunities, Lake Marie Dam is a valuable asset for water resource and climate enthusiasts in the area.
Overall, Lake Marie Dam serves as a key component in water management and recreation in Mercer, Missouri. With its significant storage capacity and flood control capabilities, the dam provides essential benefits to the local community. While it is important to monitor and address any potential risks associated with the dam, its role in enhancing the region's water resources and outdoor activities cannot be understated. For those interested in water resource management and climate resilience, Lake Marie Dam is a site worth exploring and appreciating.

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 Lake Marie Dam
Where does the data for Lake Marie 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.
