River Otters in Wisconsin Overview
River otters are semi-aquatic mammals found throughout Wisconsin. They live in rivers, lakes, and wetlands, where they hunt fish and other aquatic prey. Their sleek bodies and webbed feet make them strong swimmers.
Habitat and Behavior
In Wisconsin, river otters prefer clean waterways with abundant cover, such as undercut banks and vegetation. They are most active at dawn and dusk, using dens near the water. Their diet consists mainly of fish, crayfish, and amphibians.
Conservation and Viewing
River otter populations in Wisconsin have recovered after past declines from habitat loss and trapping. The Wisconsin Department of Natural Resources monitors their numbers and manages regulated harvest seasons. Observers can spot otters along quiet riverbanks, especially in northern Wisconsin.
