The Coast Guard just blocked off a section of the Straits of Mackinac for underwater surveys
What happened
The US Coast Guard is creating a temporary safety zone in the Straits of Mackinac. This zone will keep other boats away from two vessels conducting underwater surveys.
Why it matters
The Straits of Mackinac are a critical waterway connecting Lake Michigan and Lake Huron. This temporary closure means that commercial and recreational vessels will need to reroute or delay passage through this area. It also signals that significant underwater activity, likely related to infrastructure or environmental assessment, is underway in a sensitive location.
The signal
Watch for any public announcements about the purpose or findings of these underwater surveys, especially if they relate to the Enbridge Line 5 pipeline or other critical infrastructure.
