It is currently a eutrophic lake with elevated levels of algae blooms, nutrients, and nuisance aquatic plants.

Standing dead and dying trees (snags) on the uplands provide habitat for various species of birds and insects, including bald eagles, bats, woodpeckers, and songbirds.

Salamanders, small mammals, and invertebrates use downed and rotting logs for protection, feeding and breeding sites.

Downed trees in or at the water's edge (woody cover) are especially valuable for resting and feeding areas.

Aquatic and wetland vegetation at or near the water's edge provides critical habitat for small mammals, amphibians, reptiles, birds, and fish at all life stages.

Shawano Lake has about 24 access points, which are a combination of public and private landings and town owned fire lanes.

A county park is located on Shawano Lake, with a swimming beach and boat launch.
