Summary
With a primary purpose of recreation, this earth dam stands at a height of 23 feet and a length of 250 feet, providing a surface area of 2.82 acres for water enthusiasts to enjoy. Despite its low hazard potential, the dam's condition assessment is marked as poor, indicating potential maintenance or repair needs.
The dam's normal storage capacity is 36 acre-feet, with a maximum storage of 66 acre-feet and a drainage area of 1.26 square miles. While there is no spillway present, the dam has a maximum discharge capacity of 923 cubic feet per second. The last inspection in 2016 revealed a high risk rating of 2, highlighting the importance of ongoing monitoring and maintenance to ensure the safety and longevity of this water resource in Morgan County, Indiana.
Water resource and climate enthusiasts will find Fankboner Lake Dam to be a captivating location for outdoor activities, offering a glimpse into the intersection of human infrastructure and natural water systems. As its risk assessment indicates the need for continued attention, the dam serves as a reminder of the delicate balance between water management for recreational purposes and the need for sustainable and resilient infrastructure in the face of changing climate conditions.

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.
