Kopmann Farms - Field #N1 dam
Kopmann Farms - Field #N1
Located in Washington, Missouri, Kopmann Farms - Field #N1 is a privately owned earth dam designed by USDA NRCS in 2007 for grade stabilization purposes along the TR-MISSOURI RIVER. The dam stands at a height of 34 feet with a hydraulic height of 34 feet and a structural height of 38 feet, stretching 241 feet in length. It has a storage capacity of 51.01 acre-feet, with a normal storage of 39.76 acre-feet, serving a drainage area of 25.6 square miles.
With a low hazard potential and a moderate risk assessment rating of 3, Kopmann Farms - Field #N1 has an uncontrolled spillway type and outlet gates. The dam's condition assessment is currently marked as "Not Rated," with the last inspection conducted in January 2008. Despite its low hazard potential, the dam's risk management measures, emergency action plan preparation, and inundation maps status remain unspecified. The dam has not been modified in recent years and does not feature any associated structures or locks.
For water resource and climate enthusiasts, Kopmann Farms - Field #N1 serves as a prime example of an earth dam designed for grade stabilization purposes in Missouri. Its location in Franklin County, with a proximity to the TR-MISSOURI RIVER, showcases the importance of sustainable water management practices in mitigating risks associated with dam structures. While the dam's hazard potential is low, its moderate risk assessment warrants continued monitoring and evaluation to ensure the safety and efficiency of the infrastructure in the face of changing environmental conditions.
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 Kopmann Farms - Field #N1
Where does the data for Kopmann Farms - Field #N1 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.
