Triangle Lake Bog State Nature Preserve

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.
