Summary
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.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
