Residents in Cheboygan, Michigan have been warned that the local dam could collapse at any time due to heavy snowfall and rainfall that have contributed to rapidly rising water levels. City officials have taken emergency measures like placing sandbags and activating water pumps, but the dam continues to overflow, prompting the governor to declare a state of emergency for the county.

Why it matters

The Cheboygan Dam is a critical piece of infrastructure that helps control water flow and prevent flooding in the area. Its potential failure could lead to devastating flooding and damage to nearby homes, businesses, and transportation routes, putting the entire community at risk.

The details

The Department of Natural Resources (DNR) has activated five water pumps and is working to procure additional ones to help divert the overflowing water. All of the dam's gates are fully open, but the water levels have still risen 15 inches below the top of the dam. The US-23 bascule bridge near the dam has been closed due to concerns about erosion of its 1940s-era foundation during the flooding.

  • On Sunday, city officials placed 2,000 sandbags and activated water pumps to divert water around the dam.
  • The governor of Michigan declared a state of emergency for Cheboygan County due to the rising water levels and threat to the dam.
