Fawn Lake Dam dam
Fawn Lake Dam
Located in Franklin County, Missouri, Fawn Lake Dam is a private structure primarily used for recreation. Completed in 1969, this earthen dam stands at a height of 43 feet, with a length of 650 feet and a storage capacity of 400 acre-feet. Situated on the TR TO ST JOHNS CR river, the dam serves as a popular spot for outdoor enthusiasts seeking water-based activities in the area.
Managed by the DAM AND RESERVOIR SAFETY PROG in Missouri, Fawn Lake Dam is regulated, inspected, and enforced by state agencies to ensure its safety and compliance with regulations. Despite being classified as having a significant hazard potential, the dam is currently in satisfactory condition, as assessed in 2007. With a moderate risk level, the structure has not undergone any recent modifications and lacks emergency action plans, making it crucial for ongoing monitoring and risk management measures to be put in place.
With a spillway width of 20 feet and uncontrolled spillway type, Fawn Lake Dam has a maximum discharge capacity of 1496 cubic feet per second. The surrounding area offers a surface area of 25 acres and a drainage area of 580 acres, making it an important resource for both local residents and visitors. As climate and water resource enthusiasts, understanding the infrastructure and management of dams like Fawn Lake is essential for ensuring the sustainable use of water resources in the face of changing environmental conditions.

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 Fawn Lake Dam
Where does the data for Fawn 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 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.
