Ibeling Dam, located in Ackley, Iowa, is a private earth dam designed by USDA NRCS and completed in 1985 for purposes of fire protection, stock, and small fish pond management. 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.
