Keller Lake Dam dam
Keller Lake Dam
Keller Lake Dam, located in Hannibal, Missouri, serves primarily for irrigation purposes but also supports fire protection, stock, small fish ponds, and recreational activities. Built in 1973, this earth dam with a stone core stands at a height of 30 feet and spans 500 feet in length, offering a storage capacity of 50 acre-feet. The dam overlooks the TR-South Fabius River and has a spillway width of 12 feet, ensuring controlled water discharge during periods of excess flow.
Despite its low hazard potential, Keller Lake Dam poses a moderate risk due to its age and condition assessment not being rated. The dam has not been inspected recently, and emergency action plans or inundation maps have not been prepared, raising concerns about its safety and potential impact in the event of failure. With a risk management summary yet to be developed, stakeholders and the local community may need to consider proactive measures to ensure the dam's continued functionality and mitigate potential risks associated with its operation.
As water resource and climate enthusiasts, the unique characteristics and challenges of Keller Lake Dam present an opportunity for further exploration and engagement. Understanding the dam's role in water management and its potential impact on the surrounding environment can inspire discussions on sustainable infrastructure practices and resilience in the face of changing climate patterns. By advocating for comprehensive risk assessments, regular inspections, and emergency preparedness measures, enthusiasts can contribute to safeguarding Keller Lake Dam and promoting the long-term sustainability of water resources in the region.

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 Keller Lake Dam
Where does the data for Keller 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.
