Description: Located within a sandy glacial plain, Blomberg Lake is a 68-acre bog lake surrounded by a northern wet forest. The shallow lake (4’ maximum depth) supports only a few aquatic plants including white and yellow water-lily, and large-leaved pondweed. The surrounding wet forest is dominated by tamarack with very few black spruce. The understory varies locally from Labrador-tea to three-seeded sedge to alder. Further from the margin of the lake are many wetland grasses and sedges in the herbaceous layer such as blue-joint grass, drooping wood-reed, bristly sedge, American woolly-fruit sedge, yellow blue-bead-lily, sweet gale, marsh skullcap, and American starflower. Migratory waterfowl often use the lake and surrounding wetlands. Blomberg Lake is owned by the DNR and was designated a State Natural Area in 2003.
