East Yellow Creek A- 50 dam
East Yellow Creek A- 50
East Yellow Creek A-50 is a flood risk reduction structure located in Sullivan, Missouri, designed by the USDA NRCS and completed in 2003. This earth dam stands at a height of 27 feet and has a structural height of 31 feet, with a maximum storage capacity of 102.7 acre-feet and a normal storage of 29.2 acre-feet. The dam spans 580 feet in length, covering a surface area of 8 acres and serving a drainage area of 230.4 acres.
With a low hazard potential and a moderate risk assessment rating of 3, East Yellow Creek A-50 plays a vital role in managing flood risks in the region. The dam's primary purpose is flood risk reduction, but it also serves other purposes such as fire protection and providing habitat for fish and wildlife. Despite not being state-regulated or inspected, the structure meets the necessary guidelines and is maintained to ensure its functionality in case of emergencies.
Located in the Rock Island District and under the ownership of the local government, East Yellow Creek A-50 is a significant asset in protecting the surrounding area from potential flooding events. Its strategic design and construction by the Natural Resources Conservation Service highlight the importance of sustainable water resource management and climate resilience in safeguarding communities against natural disasters.

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 East Yellow Creek A- 50
Where does the data for East Yellow Creek A- 50 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.
