Horn Lake Dam dam
Horn Lake Dam
Located in Adair County, Missouri, the Horn Lake Dam is a private-owned structure constructed in 1959 primarily for recreation and water supply purposes. With a dam height of 32 feet and a storage capacity of 171 acre-feet, the dam serves as a low hazard potential with a "Not Rated" condition assessment. Situated on the TR-North Fork Salt River, the dam offers opportunities for recreational activities such as fishing, boating, and wildlife observation in its 10-acre surface area.
Managed by the St. Louis District of the US Army Corps of Engineers, the Horn Lake Dam does not fall under state jurisdiction or regulation. Despite its lack of state oversight, the dam's safety and integrity are regularly monitored through inspections and maintenance. With a hydraulic height of 32 feet and a drainage area of 41 square miles, the dam plays a crucial role in regulating water flow and storage in the region, contributing to the overall water resource management in the area.
Although the Horn Lake Dam does not have a designated spillway, its earth core buttress structure ensures stability and functionality. With a congressman representative of Sam Graves (R), the dam remains a vital component in the local ecosystem, providing essential water supply and recreational opportunities for residents and visitors alike. As climate change continues to impact water resources, the Horn Lake Dam stands as a testament to sustainable water management practices and the importance of balancing human needs with environmental conservation.

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 Horn Lake Dam
Where does the data for Horn 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.
