Shallow Lake is a 29-acre soft-water seepage lake with a boggy shoreline that supports a diverse assemblage of floating leaved and submergent aquatic vegetation. Characteristic plants include water-shield, white water-lily, slender water-milfoil, brown-fruited rush, beaked bladderwort, and common bladderwort. Five rare plants are also supported here. Surrounding the lake is a boggy wetland of sphagnum, sedges, ericaceous shrubs, and stunted black spruce. The floating peat mat supports species including yellow-eyed grass, white beak-rush, seven-angle pipewort, and narrow-leaved sundew. American black ducks use the lake for nesting and puddle ducks use the lake during fall migration. Shallow Lake is owned by the DNR and was designated a State Natural Area in 2007.
