Location First Found
I was down in Madison this Friday and on our way to the Union I found some water lettuce. I only saw 2 plants and I removed and discarded them on land. I attached both of the pictures I took. The location was by the UW marching band field by Marsh Dr. I grabbed some gps coordinates off of a map today and they were 43.0788 -89.4235.
