About this dam

East Yellow Creek W- 30a

East Yellow Creek W- 30a is a local government-owned earth dam located in Sullivan, Missouri, designed by the USDA NRCS. Completed in 2006, this dam serves primarily for flood risk reduction, with additional purposes including fire protection, stock or small fish pond, and fish and wildlife pond. With a dam height of 27 feet and a storage capacity of 75.7 acre-feet, it covers a surface area of 6 acres and has a drainage area of 243.2 square miles.

The dam features an uncontrolled spillway and outlet gates, with a hazard potential rated as low and a condition assessment of "Not Rated". The risk assessment for East Yellow Creek W- 30a is moderate, with a DSAC assigned date and no specific risk management measures listed. The dam is located in a picturesque setting along TR-EAST YELLOW CREEK in Rothville, with a maximum discharge of 96.4 cubic feet per second and a maximum storage capacity of 75.7 acre-feet.

Overall, East Yellow Creek W- 30a stands as an essential infrastructure for flood risk reduction in the region, providing critical protection for the surrounding areas. With its low hazard potential and moderate risk assessment, this dam represents a valuable resource for water management and climate resilience efforts in Sullivan, Missouri.

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.

FAQ

About East Yellow Creek W- 30a

Where does the data for East Yellow Creek W- 30a 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.
