Martin Dam dam
Martin Dam
Martin Dam, located in LaGrange, Missouri, is a privately owned structure built in 1991 for grade stabilization along the TR-South Wyaconda River. Standing at a height of 27 feet with a length of 339 feet, this earth dam serves multiple purposes including fire protection, stock, small fish pond, and grade stabilization. With a normal storage capacity of 24 acre-feet and a maximum storage of 36 acre-feet, the dam covers a surface area of 15 acres and drains an area of 585 square miles.
Despite being classified as having a low hazard potential, Martin Dam is considered to have a moderate risk level. It features an uncontrolled spillway with a width of 10 feet and does not have any outlet gates. While the condition assessment is not rated, the structure has not undergone any recent modifications. With no associated structures and a lack of emergency action plan preparedness, Martin Dam remains a key feature in the local water resource management system, contributing to the overall environmental health of the area.
Water resource and climate enthusiasts will appreciate Martin Dam for its role in maintaining water levels and preventing erosion along the TR-South Wyaconda River. As a privately owned structure, it stands as a testament to the importance of responsible land management and infrastructure development in ensuring the sustainability of water resources in the region. With its multiple purposes and moderate risk level, Martin Dam represents a balance between human intervention and natural processes, highlighting the complex relationship between water management and climate resilience in the face of environmental challenges.

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 Martin Dam
Where does the data for Martin 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 Low 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.
