The Holman Tailings Basin in Minnesota is a privately owned earth dam structure designed by GEI, with a primary purpose of storing tailings. This significant hazard potential dam has a height of 45 feet and a storage capacity of 10,000 acre-feet. Located in Itasca County near Trout Creek, the dam spans over 12,000 feet in length and covers a surface area of 2 acres.

Managed by the Minnesota Department of Natural Resources, the Holman Tailings Basin is subject to state regulations, permitting, and inspections to ensure its safe operation and maintenance. Despite its condition not being rated, the dam has a designated inspection frequency of 4 years, with the last inspection conducted in June 2016. Additionally, the dam's emergency action plan status and risk assessment measures are currently unlisted.

Enthusiasts interested in water resource management and climate-related infrastructure in the St. Paul District can find the Holman Tailings Basin to be a compelling subject for further study. Its unique design, location, and significance as a storage facility for tailings make it a noteworthy feature in Minnesota's environmental landscape, warranting continued monitoring and assessment to mitigate potential risks and ensure the safety of surrounding communities and ecosystems.
