Track Hindprints 2-3" (50-75mm) long, with hindfeet showing webbing between inner 4 toes; easily confused with American Beaver's when the beaver's fifth toe webbing does not print.
Sign Feeding platforms of aquatic vegetation and debris, 5–6' (1.5–2 m) across; well-established trails of flattened vegetation along marshy shores. Den is a burrow in a bank, not a lodge. At dusk, a chorus of pig-like grunts may be heard.
Scat: Elongated, cylindrical droppings found on feeding platforms or shoreline.
