Coast Guard closes part of Detroit River for rowing race June 27

The Coast Guard is closing a section of the Detroit River in Michigan from 7 a.m. to 4 p.m. on June 27, 2026, to allow a rowing regatta to take place safely. The event, organized by the Wyandotte Boat Club, will involve about 400 participants racing from Point Hennepin to the Grosse Ile toll bridge.

Why it matters: This is a standard safety measure for marine events. It keeps commercial traffic and recreational boaters away from hundreds of slow-moving rowers in cold water, reducing the risk of accidents. For most people, this means you cannot boat through that specific channel on that afternoon unless you have special permission.

Who it affects

• Recreational boaters planning to use the Detroit River or Trenton Channel between Point Hennepin and Grosse Ile toll bridge during the event hours.
