This Giant Floating Island In Lake Chippewa Has To Be Pushed By Boats Almost Every Year

Nestled within the picturesque landscape of Wisconsin’s Lake Chippewa lies a natural marvel that poses a unique annual challenge for the local community. This hidden wonder is none other than a giant floating island, a testament to the extraordinary forces of nature. The island, comprised of vegetation and trees, occasionally drifts around the lake, causing an inconvenience by blocking a vital bridge.

Lake Chippewa, known as the Chippewa Flowage, was born in 1923 when a vast swamp was transformed through flooding. Following this transformation, nature embarked on its journey. Peat bogs, once submerged, gradually rose to the surface, creating ideal conditions for the growth of plant seeds carried by wind and birds. Over the years, the lake’s landscape evolved as grasses and trees found a foothold. Surprisingly, the roots of these plants caused the floating bogs to expand.

Today, these floating islands come in various sizes, from the modest dimensions of a parking space to expansive acres. The grandest of them is the renowned “Forty Acre Bog,” on the lake’s western side, adorned with mature trees.

Almost annually, a heartwarming spectacle unfolds on Lake Chippewa as dozens of local boat owners join forces to push the floating island away from a bridge connecting the lake’s East and West sides. “It’s almost every year. It takes a community effort, and you must have the winds at your back to push them in,” remarked a resident.

The Chippewa Flowage website sheds light on the formation of these unique floating islands. They originate as mud flats that rise from the swamp’s depths. Over time, vegetation takes root, and some of the oldest islands boast trees that act as sails, propelling the entire mass across the lake.

For the locals, keeping an eye on the whereabouts of the floating island has become a daily ritual. “It’s one of the first things you look for when you come in here in the morning: Where’s the bog?” shared Denny Reyes, a resident.

Although the decades-old floating island does not relocate constantly, when it does, it presents challenges for the community by obstructing the vital bridge that serves as the sole passage between the lake’s East and West sides. To resolve this issue, boat owners unite, forming a flotilla of vessels that collectively exert their efforts. Last year, 25 boats successfully nudged the floating island away from the bridge.

Moving the island requires precision, as merely relocating it a short distance may result in its return within days. Local homeowner Greg Kopke explained, “When we move it, we gotta get it in the right spot, or it can be back in a couple of days.”

These floating islands, such as the Forty Acre Bog, are legally protected and home to diverse animal species. Consequently, they cannot be dismantled or disrupted, highlighting the delicate balance between human convenience and environmental conservation.

The annual ritual of relocating Lake Chippewa’s floating island is a testament to the coexistence of humanity and nature, a heartwarming display of community unity, and a reminder of the importance of preserving the unique habitats that enrich our world.
