Never seen this before

[bigarm]

I was a the Cat today and was up by the damn area fishing a small hump that is out in the middle of the main arm facing the damn. When all of a sudden I got this eerie feeling that I was being stalked in a menacing way. I looked all around and seen absolutely nothing. Was doing a little casting when I heard a splash splash. Looked around nothing but the fear was building inside. Now I am approx. 300yrds from one shore and maybe 3-400 yards to the other. Now keep in mind there is some 40 to 50 ft of water from shore to shore. I kept looking and then I saw it. It was watching me but was determined to get to the other side was not going to let anything stand in its way. The only obstacle that was in its way was me and 400 yrds of open water. I got out of its way and it went on. Never seen this before and the fear will always remain.
