Turtle-Flambeau Detached Dike 1, located in Iron, Wisconsin, is a public utility structure managed by the Federal Energy Regulatory Commission. Built in 1926, this earth dam stands at a height of 12 feet and has a storage capacity of 239,000 acre-feet. The dam plays a crucial role in flood control and water management in the region, with a high hazard potential due to its significant storage capacity.

Associated with eight other structures, Turtle-Flambeau Detached Dike 1 has not been inspected since September 2019, with a high risk potential and no condition assessment available. While it meets regulatory guidelines, there is no Emergency Action Plan (EAP) prepared, raising concerns about emergency preparedness. With a history of serving the community for nearly a century, ongoing monitoring and maintenance are essential to ensure the safety and integrity of this vital water resource infrastructure.

As climate change continues to impact water resources and infrastructure, the importance of regular inspections, risk assessments, and emergency preparedness for structures like Turtle-Flambeau Detached Dike 1 cannot be overstated. With its strategic location and significant storage capacity, this dam plays a crucial role in protecting downstream communities and ecosystems from potential flooding events. Ongoing collaboration between federal and state agencies is essential to ensure the continued safety and effectiveness of this key water management structure.
