Deer Run Lake Dam dam
Deer Run Lake Dam
Deer Run Lake Dam in Missouri, completed in 1967, is a privately owned earth dam primarily used for recreation. With a height of 43 feet and a length of 700 feet, the dam holds a storage capacity of 559 acre-feet and covers a surface area of 39 acres. Situated on the TR to Little St Francis River in Madison County, the dam is regulated by the DAM AND RESERVOIR SAFETY PROG and falls under the jurisdiction of the state.
Despite its satisfactory condition assessment, the dam has a high hazard potential, as indicated by its moderate risk assessment rating. The spillway type is uncontrolled with a width of 90 feet, allowing for a maximum discharge of 8392 cubic feet per second. While the last inspection in 2016 deemed the dam to be in good shape, it is subject to regular monitoring with an inspection frequency of 3 years to ensure the safety of the surrounding community.
For water resource and climate enthusiasts, Deer Run Lake Dam serves as an important recreational structure within the St. Louis District. Its presence not only provides a source of leisure for locals but also highlights the critical role of dam safety programs in maintaining the integrity of aging infrastructure. As climate change continues to impact water resources, the upkeep and monitoring of dams like Deer Run Lake Dam are essential for mitigating risks and ensuring the resilience of our water systems.

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 Deer Run Lake Dam
Where does the data for Deer Run 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 High 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.
