Located in Lake Panorama, Iowa, the Gibson North Dredge Spoil Containment structure is a privately-owned earth dam designed by John Milligan of MHF Engineering. Completed in 2006, this dam stands at a height of 104 feet with a length of 2,270 feet, providing a storage capacity of 1,625 acre-feet for the Tr-Lake Panorama (Middle Raccoon River). The dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections to ensure its fair condition and significant hazard potential.

Despite its uncontrolled spillway type and moderate risk assessment, the Gibson North dam remains a crucial asset for water resource management in Guthrie County. With a drainage area of 1.83 square miles, this structure plays a vital role in flood control and environmental protection for the surrounding area. As climate change continues to impact water resources, the maintenance and upkeep of dams like Gibson North are essential for ensuring the safety and resilience of communities against potential disasters.
