The name of the stream is translated into English as "wild brook"; this is thought to be because of the way the stream suddenly grows after heavy rain. This effect is attributed to the fact that the stream is approximately 9 kilometres long and passes down steep hills which quickly channel the rain that comes from the Atlantic.
