Largest rodent in North America. They can live 10-20 years.

Wide flat tail used as rudder when swimming and to slap the water to warn other beavers of predators.

The oil comes from a gland and makes the fur waterproof.

They have clear eyelids that work like goggles and their ears and nose close up while under water so they can hold breath for up to 15 minutes.

They have very large front teeth that never stop growing, so they chew on trees to trim them down.

One beaver can chew down as many as 200 trees per year.

Beavers often cut trees near Bluff Lake and Sand Creek. Look for stumps that have been chewed to a point.

Bluff lake paints many of their trees with sand and brown to stop beavers from chewing down too many trees.
