Summary
With a height of 28 feet and a length of 275 feet, the dam has a storage capacity of 36 acre-feet and serves the TR- BEAVER CR. stream. The dam is under the regulatory oversight of the Iowa Department of Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
Despite being classified as low hazard potential and having a moderate risk assessment score of 3, the condition of Ibeling Dam is currently not rated. The dam does not have outlet gates or a controlled spillway, but its uncontrolled spillway type allows for natural overflow in case of excess water. While the dam has not been modified in recent years and lacks certain emergency preparedness measures like an EAP or inundation maps, it continues to provide essential water resource management functions for the surrounding area. With its location in a rural setting and minimal associated structures, Ibeling Dam remains a key asset for local water conservation efforts and climate resilience.

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.
