Clifford Hoehn Dam dam
Clifford Hoehn Dam
Clifford Hoehn Dam, located in Perry County, Missouri, stands as a testament to the successful collaboration between the private owner and the USDA NRCS in addressing flood risk reduction. Completed in 2006, this earth dam boasts a height of 25 feet and a hydraulic height of 20 feet, with a storage capacity of 125.31 acre-feet. With its primary purpose being flood risk reduction, the dam plays a crucial role in safeguarding the surrounding area from potential inundation during high water events.
Situated on Apple Creek, this controlled spillway dam spans 498 feet in length and covers a surface area of 5 acres. Despite its low hazard potential, the dam is rated as having a very high risk due to its critical function in flood control. While the dam's condition assessment is currently not rated, its risk management measures are yet to be fully detailed. With no outlet gates and a lack of associated structures, the focus remains on the dam's core function of protecting the local community from the impacts of flooding.
In the hands of a private owner, Clifford Hoehn Dam continues to serve as a vital infrastructure for flood risk reduction in the region. With the expertise of the USDA NRCS behind its design, the dam stands as a reliable bulwark against potential flood events, ensuring the safety and security of Old Appleton and its surrounding areas along Apple Creek.
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 Clifford Hoehn Dam
Where does the data for Clifford Hoehn Dam 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.
