Soap Creek Watershed Site 90-102 dam
Soap Creek Watershed Site 90-102
Soap Creek Watershed Site 90-102 in Wapello, Iowa, is a local government-owned earth dam designed by the USDA NRCS with a primary purpose of flood risk reduction. Completed in 2007, this dam stands at a height of 30 feet and spans 365 feet in length, with a storage capacity of 92 acre-feet. Situated on a tributary to Little Soap Creek, this structure plays a crucial role in managing water flow and reducing the risk of flooding in the area. With a low hazard potential and not yet rated in terms of condition assessment, this dam serves as an essential infrastructure for water resource management in the region.
Located in the Rock Island District, this watershed site is under the jurisdiction of the Iowa DNR for regulation, permitting, inspection, and enforcement. The surrounding area benefits from the dam's ability to control discharge and store water during periods of high flow, ultimately protecting downstream communities and ecosystems from potential flood damage. With a spillway width of 16 feet and a drainage area of 0.38 square miles, this site demonstrates a commitment to sustainable water resource management and climate resilience.
As water resource and climate enthusiasts, the Soap Creek Watershed Site 90-102 serves as a prime example of effective infrastructure for flood risk reduction in the state of Iowa. Managed by local government authorities and designed by the USDA NRCS, this earth dam plays a crucial role in mitigating the impact of extreme weather events and ensuring the safety of nearby residents. With its strategic location on a tributary to Little Soap Creek, this site highlights the importance of proactive measures in managing water resources and adapting to the challenges posed by a changing climate.
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 90-102
Where does the data for Soap Creek Watershed Site 90-102 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.
