Milfoil Warrior 1

This floating conveyor belt is used to rip the nasty Asian milfoil from the lake bottom shallows and then, as will be seen in later photos, deliver it to a dump truck to be disposed of.  As little as a leaf or stem of the plant is sufficient to infest a lake, which is what happened in Lake Harriet, probably a decade ago.   Budget cuts reduced use of the machine, leading to longer periods and wider swatches of the lake remaining covered by the weed.
