Hoblitzelle Upper Lake Dam dam
Hoblitzelle Upper Lake Dam
Hoblitzelle Upper Lake Dam, located in St. Charles, Missouri, is a private dam primarily used for recreation purposes. Standing at a height of 34 feet, the earth dam is classified as a buttress type with a storage capacity of 91 acre-feet. The dam overlooks the TR Missouri River and offers a serene setting for water resource and climate enthusiasts to enjoy various outdoor activities.
Despite its recreational appeal, the dam is classified as having a high hazard potential and is currently not rated for its condition assessment. The dam has not been inspected recently, and there is no emergency action plan in place. With a drainage area of 90 square miles, the dam serves as a critical infrastructure for managing water resources in the region, making it essential for stakeholders to prioritize its maintenance and safety.
As part of the Kansas City District, the Hoblitzelle Upper Lake Dam warrants attention from local authorities and dam safety regulators to ensure its continued functionality and safety. With its picturesque location and important role in water management, this dam presents an opportunity for water resource and climate enthusiasts to engage in discussions about the importance of maintaining and monitoring such structures for sustainable development and environmental resilience.
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.
Plan around the weather

About Hoblitzelle Upper Lake Dam
Where does the data for Hoblitzelle 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.
