The name and hometown of the child that was rescued is not being released.
The incident happened just after 2 p.m. while Station Grand Haven crewmembers were preparing their response boat for training. A crew launched a 25-foot response boat and other station personnel responded the scene by foot.
The rescue crews discovered four people trying to assist the boy. It was reported to the Coast Guard that the boy had fallen from the east basin at Escanaba Park after losing his balance.
The boy reportedly sustained head injuries during the fall.
The Coast Guard transported the boy to shore and contacted emergency medical services. Other crewmembers assisted the remaining four people out of the water.
Station Grand Haven personnel conducted an initial assessment and kept the boy conscious while awaiting paramedics.
Paramedics placed the boy on a backboard and transported him to North Ottawa Community Hospital.
The boy's condition is unknown at this time. The four people who went into the water to rescue the boy did not require any medical assistance, the Coast Guard said.
“It is important that people exercise caution whenever recreating in or near the water,” said Petty Officer 2nd Class Greg Mattson, the coxswain and officer-of-the-day at Station Grand Haven. “Parents should remain extra vigilant on piers in the Great Lakes, because many of them lack handrails. It may only take the slightest misstep to cause an emergency situation.”
