A watersnake (shown above and below) was swimming in the spillway over Memorial Day weekend. Click photos to zoom in.
I took the picture above and the two snake pictures below while standing in the same spot (by the edge of Lake Tamarack at the spillway), yesterday. The snake is a nonvenomous watersnake. It slithered into the water and swam about four feet from the edge, as I approached the lake. Then it stayed perfectly still, holding its head above water, for several minutes as I watched it and took some pictures.
