Are there muskrat's in Lake Wateree? I have never seen a muskrat before, but this little critter looked like a giant rat that can swim really well. Also I caught a mystery fish for the second time while getting bait. It was the same size in length as a gizzard shad, but it was a lot skinnier. It was also very oily like a shad so I am guessing its a relative, but just don't know what it is. It was all one color which was a grayish color. It may be a blueback, but its back was not blue. It was all one color. And again I have never seen a blueback in person so I wouldn't really know and it was dark so I may have not had enough light to see the blue. And it swims really fast. It took quite a few tries to get it out of the bait tub. And the only cat I caught tonight came on this guys head, not that has anything to do with anything.
