It is incredible how well deer can swim though. I have encountered a lot of deer at night swimming across the Mississippi and Wolf river. One spring when the Miss was up about 4 or 5 feet, a doe came out on the MN side, jumped in, and made the swim across. I was absolutely stunned to see how straight it swam. Heck, if it had been me, I wouldn’t have made the main channel marker and would be about 50 miles down stream.
