Ahquabi Dredge Spoil Containment Dam 5a, located in Indianola, Iowa, serves as a crucial structure for debris control on TR- SQUAW CREEK. Constructed in 1995 by BUTTS ENGINEERING, this earth dam stands at 19 feet high and spans 519 feet in length. With a storage capacity of 113 acre-feet, the dam primarily functions to prevent debris from causing blockages and flooding in the area. Despite being classified with a low hazard potential, the dam has not been formally rated for its condition.

Managed by the Iowa Department of Natural Resources (IOWA DNR), the dam is subject to state regulation, permitting, inspection, and enforcement to ensure its structural integrity and effectiveness in preventing debris-related issues. While it has a moderate risk assessment rating of 3, the dam has not had an Emergency Action Plan (EAP) prepared or updated recently, raising concerns about emergency response preparedness. Overall, Ahquabi Dredge Spoil Containment Dam 5a serves as a critical piece of infrastructure for water resource management in the region, warranting continued monitoring and maintenance to uphold its functionality and safety.
