Spring Lake Dam dam
Spring Lake Dam
Located in Jefferson, Missouri, the Spring Lake Dam stands as a vital structure for recreation and water resource management. Built in 1976, this earth dam, with a height of 42 feet and a length of 600 feet, serves as a key component in regulating the flow of the TR-Falling Rock Branch river. With a normal storage capacity of 133 acre-feet and a maximum storage of 178 acre-feet, the dam provides essential water storage for the surrounding area.
Managed by a private owner but regulated by the Dam and Reservoir Safety Program of Missouri, the Spring Lake Dam has a high hazard potential but is deemed to be in satisfactory condition. Inspected every two years, the dam boasts a spillway width of 12 feet and an uncontrolled spillway type. Despite the moderate risk level associated with the dam, it plays a crucial role in water conservation and flood control efforts in the region.
For water resource and climate enthusiasts, the Spring Lake Dam in Missouri is a fascinating structure that combines both recreational and practical purposes. Its design, construction, and maintenance are closely monitored to ensure the safety of the surrounding communities and the ecological balance of the area. With its strategic location and significant storage capacity, the Spring Lake Dam remains a noteworthy landmark in the local water resource management landscape.

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.
Plan around the weather

About Spring Lake Dam
Where does the data for Spring 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.
