Wappapello Dam - Saddle Dike 1 dam
Wappapello Dam - Saddle Dike 1
Wappapello Dam - Saddle Dike 1, located in Wayne County, Missouri, is a vital piece of infrastructure managed by the US Army Corps of Engineers for flood risk reduction on the St. Francis River. Completed in 1941, this earth dam stands at a height of 114 feet and has a storage capacity of 1,134,600 acre-feet. With a surface area of 23,200 acres and a drainage area of 1,310 square miles, the dam plays a crucial role in managing water levels to protect downstream communities.
The dam's significant hazard potential underscores the importance of ongoing risk management measures implemented by the US Army Corps of Engineers. Regular inspections, maintenance, and emergency preparedness activities are integral to ensuring the dam's structural integrity and readiness to handle extreme weather events. Despite the inherent risks associated with dam operations, the USACE remains dedicated to collaborating with local stakeholders, emergency managers, and the public to enhance awareness and preparedness for potential dam-related emergencies.
As a key component of the region's flood control infrastructure, Wappapello Dam - Saddle Dike 1 serves as a critical safeguard against inundation and water release during periods of heightened risk. The USACE's proactive approach to monitoring and addressing potential threats underscores their commitment to safeguarding communities and protecting natural resources in the face of evolving climate challenges.
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 Wappapello Dam - Saddle Dike 1
Where does the data for Wappapello Dam - Saddle Dike 1 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 Significant 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.
