Smoke from the blaze was visible from across the river as well as at the intersection of U.S. 31 and Jackson Street in Grand Haven.
Officials from Spring Lake Township Fire Department said just a little over half an acre burned in the blaze reported just after 2 p.m.
David Bosse, 206 South St., watched as Crockery Township firefighters manipulated their all-terrain vehicle into the swampy area.
He climbed onto a brush pile to get a better vantage of the firefighters disappearing in the cattails.
“I called 911, but they already knew about it,” he said. “I’ve been keeping an eye out on my property to watch for kids out there.
The cause of this fire, and the one from two weeks ago, was unknown.
“The cattails are so dry, it doesn’t take much to get them started,” one firefighter said.
Firefighters leaving the swamp discovered a large snapping turtle with a scorched shell.
They used their water from their backpack tanks to soak down the one-foot-long snapper.
It eventually moved out of the way.
Firefighters were on the scene about an hour.
