I believe it. I was boating in after a duck hunt a couple of years ago and decided to check out the beaver or whatever that was moving out in the middle of lake. It was a doe that I ended watching swim across the lake for about 15 minutes until it got to the other side and then ran off full spead! Glad it wasn't a monster buck, I would have spent the rest of the season sitting out in a stand in the middle of the lake.
