Mononame 805 Dam
Mononame 805
Mononame 805, a privately owned dam in Cape Girardeau, Missouri, stands as a testament to the importance of water resource management for recreational purposes. Completed in 1960, this earth dam with a height of 15 feet and a storage capacity of 80 acre-feet is situated on TR HUBBLE CREEK. Despite its low hazard potential, Mononame 805 has not been rated for its condition assessment, highlighting the need for ongoing monitoring and maintenance to ensure its safety and functionality.
With no state jurisdiction, regulation, permitting, or inspection, the responsibility for the upkeep of Mononame 805 lies solely with its private owner. The dam's primary purpose of recreation underscores the significance of proper management to prevent any potential risks or hazards. Although not part of the USACE, this structure plays a vital role in water resource management within its local community, providing opportunities for leisure and enjoyment while also serving as a reminder of the importance of sustainable water practices in the face of climate change.
As water resource and climate enthusiasts, the data surrounding Mononame 805 serves as a call to action for increased vigilance and stewardship of our natural resources. By understanding the intricacies of dam structures like Mononame 805 and advocating for proper maintenance and oversight, we can help ensure the safety and sustainability of our water systems for generations to come. Let this dam be a reminder of the delicate balance between human recreation and environmental conservation, urging us to prioritize responsible water resource management in the face of a changing climate.

About Mononame 805
Where does the data for Mononame 805 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 below 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.
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.
