They can hit their tail on the surface of the water to make a splash, this warns other beavers of danger. They use their tail for other stuff too.
Beavers have tails a lot of reasons. For one it helps them turn when they're swimming, it helps them swim fast to get away from predators that can swim, and its a warning call. When there's a predator around they slap their tails against the water to tell the other beavers there's a predator nearby.
The fur can store little heat bubbles so when they go under cold water they don't get too cold and so they can stay in water longer. Also they can live in cold habitations so they need to stay warm

They use their flat tails to slap the water, to let other beaver know where they are, and where food is. They also slap their tails to alert other beavers of danger.
