Black Upper Lake Dam dam
Black Upper Lake Dam
Black Upper Lake Dam in St. Francois, Missouri, stands as a crucial structure for fire protection, stock, and small fish pond purposes. Completed in 1976, this private Earth dam, with a height of 30 feet and a storage capacity of 90 acre-feet, serves as a vital resource in the area. Situated on the TR-ST FRANCIS RIVER, this dam not only safeguards the surrounding community but also provides recreational opportunities for visitors.
Despite its significant role, Black Upper Lake Dam is not regulated by the state and has a high hazard potential. The dam, constructed with a buttress core type, maintains a structural height of 30 feet and a surface area of 2 acres. While the dam has not been rated for its condition, its importance in ensuring fire protection and supporting local wildlife underscores the need for regular inspection and maintenance to prevent any potential risks.
With its location in SYENITE and under the jurisdiction of the Kansas City District, Black Upper Lake Dam remains a critical asset for water resource and climate enthusiasts. As it continues to fulfill its primary purposes and offer recreational opportunities, it is essential to recognize the importance of safeguarding and maintaining this structure to ensure the safety and well-being of the community and the environment.
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 Black Upper Lake Dam
Where does the data for Black Upper 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.
