There was once a woman who had been traveling through the woods for some time. She wished to take a break from her travels by going for a swim. She found a nearby stream and decided to dam the stream so that she could swim around. Once she submerged into the water, she did not want to leave.
The stream asked her to leave the stream and allow the water to pass as it had been, but the woman refused. Since the woman refused, the stream decided to turn her into a beaver, and transformed the leather apron she was wearing into a beaver tail.
