Whitney Tailings, also known as Pierce-Whitney T Basin, is a private-owned tailings structure located in St. Louis County, Minnesota. Completed in 1960, the earth dam stands at a height of 37 feet and stretches for 9200 feet, with a storage capacity of 4825 acre-feet. The primary purpose of Whitney Tailings is for storing tailings, and it is regulated by the Minnesota Department of Natural Resources.

Despite being categorized as low hazard potential with a condition assessment of "Not Rated," Whitney Tailings has not been inspected since November 2010. The dam is situated in a closed system near a river or stream, with a drainage area of 16 acres. The structure's emergency action plan status, risk assessment, and risk management measures are currently not available, raising concerns about the readiness for potential hazards or emergencies.

Given the lack of recent inspections and data on emergency preparedness, water resource and climate enthusiasts may find Whitney Tailings an intriguing case study in monitoring and managing potential risks associated with tailings storage facilities. The structure's location in a populated area and its proximity to a closed water system highlight the importance of proactive monitoring and maintenance to ensure the safety and resilience of water resources in the region.
