This Looks Like Bad News for Fishing...

I made these photos last week on Sam Rayburn. I am pretty sure this is Giant Salvina, a very hard to control invasive plant. It was floating around everywhere in small patches like this one. It's method of operation is to blanket a lake, kill the wave action therefore taking the oxygen out of the water.

Up side to this is there is a researcher at Stephen F. Austin State University using this plant as a focus of his cancer research. Hope he has some luck, it would help more ways than one.
