pond's owners have no idea how the hydrilla came to be there; U S Army Corps of Engineers and WI DNR personnel believe it was brought in with nursery-stocked plants; all plants in the pond were killed using Aquathol K, and the pond was drawn down completely and froze the winter of 2007-2008; verified & pressed, 19 Jul 2007, labeled & mounted, 17 Oct 2009, when the DNR finally released the location, by T.S.
