Triangle Lake Bog State Nature Preserve

Due to parking area and driveway maintenance, Triangle Lake Bog will be closed on Tuesday October 3rd.

Preserving 61 acres in Portage County

One of the best examples of a kettle lake bog in Ohio containing carnivorous plants, tamarack and a floating sphagnum mat.

Triangle Lake Bog is one of the finest and least disturbed sphagnum kettle-hole bogs in Ohio. The vegetational zone surrounding this glacial kettle lake follows the classic pattern of boreal bogs.

A floating sphagnum mat with swamp loosestrife, leatherleaf and tamaracks surrounds the dark acidic waters of the bog lake.

Significant species found here include northern pitcher-plant, round-leaved sundew, leatherleaf, highbush blueberry, large cranberry, poison sumac and catberry.
