Soap Creek Watershed Site 4-99 dam
Soap Creek Watershed Site 4-99
Soap Creek Watershed Site 4-99, located in the beautiful county of Appanoose, Iowa, is a flood risk reduction structure designed by the USDA NRCS and completed in 2004. This earth dam stands at a height of 29 feet and spans 485 feet in length, serving the primary purpose of flood risk reduction for the local community. With a storage capacity of 129 acre-feet and covering a surface area of 5 acres, this structure plays a crucial role in managing water flow in the area.
Managed by the Iowa DNR and regulated by the state, Soap Creek Watershed Site 4-99 boasts a low hazard potential and a moderate risk assessment score. Despite not being rated for condition assessment, this structure meets state permitting and inspection requirements, ensuring its safety and effectiveness in flood control. Situated along the Tr-Mormon Creek, this site is a vital component of water resource management in the region, offering protection to the surrounding areas from potential flooding events.
With its uncontrolled spillway and soil foundation, Soap Creek Watershed Site 4-99 stands as a testament to effective water resource management in Iowa. Supported by the local government and designed to mitigate flood risks, this structure represents a harmonious balance between human development and environmental conservation. As water resource and climate enthusiasts, we can appreciate the importance of such structures in safeguarding communities and ecosystems from the impacts of extreme weather events, making Soap Creek Watershed Site 4-99 a key player in the sustainable management of water resources in the region.
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.

About Soap Creek Watershed Site 4-99
Where does the data for Soap Creek Watershed Site 4-99 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.
