Mononame 47 dam
Mononame 47
Mononame 47 is a privately owned earth dam located in Schell City, Missouri, on the TR Osage River. Built in 1972 for recreational purposes, this 12-foot tall structure has a storage capacity of 96 acre-feet and a surface area of 15 acres. With a low hazard potential and a condition assessment that is currently not rated, Mononame 47 serves as a picturesque spot for water resource and climate enthusiasts to explore.
Managed by the Kansas City District of the US Army Corps of Engineers, Mononame 47 has not been modified over the years and does not have a designated spillway. Despite its low hazard potential, the dam's emergency action plan and risk assessment measures are currently not assessed or updated. With its serene surroundings and the beauty of the TR Osage River, Mononame 47 offers a tranquil setting for outdoor recreation and wildlife observation, making it a must-visit destination for nature lovers and water resource enthusiasts in Missouri.
As an unregulated and uninspected dam, Mononame 47 presents a unique opportunity for visitors to appreciate the natural beauty of Vernon County while also recognizing the importance of proper dam maintenance and emergency preparedness. With its historical significance dating back to the early 1970s, this earth dam stands as a testament to the harmonious coexistence of human recreation and environmental conservation along the banks of the TR Osage River.
Dam data reference
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.
Plan around the weather

About Mononame 47
Where does the data for Mononame 47 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.
