Kelly I will pull some of this grass out of the water and get a good picture. Later in the growing season perhaps it will show some better identifying traits. As it first starts growing, I think it puts our two grass blades and sometimes starts to curl partially like a question mark while still under water. And these first plants after rising above the surface lay a blade of grass on the surface about 6 inches to nearly a foot long. The blades are narrow, 1/16 inch or so. I can see some that are growing further out from the shore and I found what looks to be a thick patch that hasn't reached the surface yet. I would have never spotted it except the sun was really bright one day when I could see it. I have had a couple of Wood Ducks families this season, maybe they could have brought it to the pond.
