Rush Island Fly Ash dam
Rush Island Fly Ash
Rush Island Fly Ash is a public utility structure located in Jefferson, Missouri, along the Isle Du Bois Creek. It is regulated by the DAM AND RESERVOIR SAFETY PROG, with the Missouri state agency overseeing permitting, inspection, and enforcement. The dam is an earth buttress type with a height of 46 feet and a hydraulic height of 40 feet, serving to store water for a normal capacity of 386 acre-feet and a maximum capacity of 445 acre-feet.
The dam has a low hazard potential and is in satisfactory condition according to the latest assessment in May 2015. It has a moderate risk assessment rating of 3 and is inspected every 5 years to ensure its integrity and safety. Rush Island Fly Ash features an uncontrolled spillway with a width of 200 feet and needle outlet gates. The structure poses minimal risk but plays a crucial role in managing water resources in the area.
Enthusiasts of water resources and climate will find Rush Island Fly Ash an interesting structure to study, given its unique design and purpose. Its location in Missouri and association with a public utility make it a significant part of the local infrastructure. With a focus on dam safety and risk management measures, this structure showcases the importance of monitoring and maintaining water resources for sustainable use and environmental protection.

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 Rush Island Fly Ash
Where does the data for Rush Island Fly Ash 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.
