Mononame 563 dam
Mononame 563
Mononame 563, located in Washington, Missouri, is a privately owned earth dam constructed in 1968 for recreational purposes along the Henson Branch river. Standing at a height of 20 feet with a storage capacity of 64 acre-feet, this dam covers a surface area of 6 acres and drains a watershed of 98 acres. Despite its low hazard potential and not being state regulated, Mononame 563 serves as a vital recreational resource for the local community.
Managed by private owners, this dam has not been rated for its condition assessment and lacks emergency action plans or inundation maps. Although it has not undergone recent inspections, its low hazard potential suggests a minimal risk to the surrounding area. The Kansas City District oversees its operation, but with no federal agency funding or involvement in its construction or regulation, Mononame 563 remains primarily under private ownership and management.
For water resource and climate enthusiasts, Mononame 563 presents an interesting case study of a privately owned dam providing recreational benefits in a rural setting. Its location in Richwoods, Missouri, coupled with its modest size and storage capacity, highlights the importance of smaller-scale infrastructure in supporting local communities and enhancing outdoor recreational opportunities. As one of many such structures across the country, Mononame 563 exemplifies the diverse landscape of water resource management and the intersection of public and private interests in ensuring the sustainable use of natural resources.
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
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Mononame 563
Where does the data for Mononame 563 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.
