River Otter Chicago Overview
River otters are semi-aquatic mammals found in the Chicago area, particularly along the Chicago River and nearby waterways. They feed on fish and invertebrates and are active year-round.
Where to Spot River Otters in Chicago
Sightings are common near the Chicago Riverwalk, Montrose Harbor, and the North Branch Canal. They are most visible at dawn and dusk near calm stretches of water.
Conservation and Habitat
Improved water quality and habitat restoration have helped river otters return to urban Chicago. The Illinois Department of Natural Resources tracks sightings and notes that clean rivers support healthy otter populations.
