Mononame 41 dam
Mononame 41
Mononame 41, located in Iron, Missouri, is a privately owned Earth dam completed in 1965 for the primary purpose of water supply. Standing at a height of 23 feet, this dam on TR Crooked Creek has a storage capacity of 74 acre-feet and covers a surface area of 6 acres within a drainage area of 10 square miles. While it has a low hazard potential and is not currently rated for its condition, Mononame 41 plays a crucial role in providing water resources to the surrounding area.
Managed by the St. Louis District of the US Army Corps of Engineers, Mononame 41 serves as a reliable water source for the city of Dillard and the local community. Despite lacking certain regulatory and inspection measures, this dam remains an essential infrastructure for maintaining water supply and ensuring water security in the region. With its strategic location and historical significance, Mononame 41 stands as a testament to the importance of sustainable water resource management in mitigating the impacts of climate change on water availability.
As climate enthusiasts and water resource advocates, it is crucial to recognize the value of structures like Mononame 41 in safeguarding water resources for future generations. By understanding the significance of dams like these in providing water supply and managing water resources effectively, we can work towards sustainable solutions that address the challenges posed by a changing climate. Mononame 41 serves as a reminder of the intricate relationship between water resources, infrastructure, and climate resilience, highlighting the need for proactive measures to ensure the continued availability and quality of water for both present and future needs.

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 Mononame 41
Where does the data for Mononame 41 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.
