Hammel Lake Dam dam
Hammel Lake Dam
Hammel Lake Dam in St. Charles, Missouri, serves primarily as a debris control structure to protect the area from potential hazards. Constructed in 1969, this earth dam stands at a height of 29 feet and has a storage capacity of 62 acre-feet. While the dam is privately owned and not regulated by the state, its low hazard potential and condition assessment of "Not Rated" suggest that it is well-maintained and poses little risk to the surrounding community.
Situated on TR Calloway Creek, Hammel Lake Dam plays a vital role in fire protection, stock management, and serving as a small fish pond. With a normal storage capacity of 35 acre-feet and a surface area of 4 acres, the dam helps manage water resources in the area. Despite its age, the dam's structure remains intact, with no reported incidents or need for major modifications. Its location within the Kansas City District adds to its importance as a key infrastructure for water management in the region.
For water resource and climate enthusiasts, Hammel Lake Dam offers a fascinating case study of a privately owned structure designed for multiple purposes. Its ability to control debris while providing additional benefits like fire protection and recreational use showcases the versatility of dams in managing water resources. With a history dating back to the late 1960s, this dam stands as a testament to the importance of maintaining and monitoring infrastructure to ensure the safety and sustainability of water systems in the face of changing climate 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 Hammel Lake Dam
Where does the data for Hammel 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 Low 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.
