Soap Creek Watershed Site 68-80 dam
Soap Creek Watershed Site 68-80
Soap Creek Watershed Site 68-80 is a significant flood risk reduction structure located in Floris, Iowa. Owned by the local government and regulated by the Iowa Department of Natural Resources, this earth dam stands at a height of 41 feet and stretches 830 feet in length. Completed in 2009, it serves the primary purpose of flood risk reduction for the surrounding area, with a maximum storage capacity of 563 acre-feet and a normal storage capacity of 108 acre-feet.
Situated in Monroe County, Iowa, this watershed site plays a crucial role in managing water flow and reducing flood hazards in the region. With a low hazard potential and a condition assessment of "Not Rated," this structure provides essential protection for the community against potential flooding events. The dam has a spillway width of 40 feet and is primarily constructed of stone core and soil foundation, ensuring its stability and effectiveness in flood control measures.
Managed by the USDA NRCS and located in the Rock Island District, Soap Creek Watershed Site 68-80 is a key component in the overall water resource management strategy for the area. With a drainage area of 1.88 square miles and a maximum discharge capacity of 573 cubic feet per second, this structure exemplifies the importance of proactive flood risk reduction measures in safeguarding communities and natural resources against the impacts of climate change.
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 68-80
Where does the data for Soap Creek Watershed Site 68-80 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.
