The dam's low hazard potential and not rated condition assessment make it a safe and peaceful destination for outdoor activities.
Managed by the St. Louis District of the US Army Corps of Engineers, Koch Lake Dam offers a surface area of 4 acres and a drainage area of 180 acres, providing ample opportunities for water-based recreation and wildlife observation. Despite not being regulated by the state of Missouri, the dam's design as an earth dam with a buttress core adds to its structural integrity and reliability for long-term use. Whether you're interested in fishing, boating, or simply enjoying the scenic beauty of the surrounding area, Koch Lake Dam is a hidden gem waiting to be explored.
For those seeking a tranquil escape in nature, Koch Lake Dam in Hayden, Missouri, is a must-visit destination. With a normal storage capacity of 37 acre-feet and a maximum storage of 68 acre-feet, this dam offers a peaceful retreat for outdoor enthusiasts. Surrounded by the beauty of Maries County and the Gasconade River, Koch Lake Dam is a testament to the importance of responsible water resource management and the preservation of our natural landscapes. Whether you're looking to unwind with a leisurely boat ride or simply soak in the serenity of the water's edge, Koch Lake Dam is sure to captivate the hearts of water resource and climate enthusiasts alike.
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 Koch Lake Dam
Where does the data for Koch Lake 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.
