Soap Creek Watershed Site 4-86 dam
Soap Creek Watershed Site 4-86
Soap Creek Watershed Site 4-86, located in Selma, Iowa, is a local government-owned dam designed by the USDA NRCS to primarily serve as a flood risk reduction structure. Completed in 2010, this earthen dam stands at a height of 30 feet and spans a length of 900 feet, with a storage capacity of 115 acre-feet. With a drainage area of 0.41 square miles and a maximum discharge of 39 cubic feet per second, this dam plays a crucial role in managing water flow in the region.
Managed by the Iowa DNR, Soap Creek Watershed Site 4-86 is regulated, permitted, inspected, and enforced by the state to ensure its structural integrity and compliance with safety standards. Despite being labeled as having a low hazard potential and not yet rated for its condition, this dam continues to contribute to flood risk reduction efforts in the area. With its foundations resting on soil and core made of stone, this dam serves as a key component in protecting the surrounding community from potential water-related disasters.
With its location in the Appanoose County, the Soap Creek Watershed Site 4-86 is a vital infrastructure that enhances water resource management in the region. As a part of the flood risk reduction system, this dam showcases the collaborative efforts between local government entities and federal agencies like the USDA NRCS. By maintaining this structure and ensuring its proper operation, stakeholders work towards safeguarding the community from the impacts of extreme weather events and climate change.

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 4-86
Where does the data for Soap Creek Watershed Site 4-86 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.
