CommentsI did not take pictures of large clumps of hydrilla removed from lower unit of research vessel, however, samples were positively ID's as Hydrilla independently by myself and Lab manager of the Periphyton lab at FIU. Mats were so dense in regions of the C-111 canal (including center of canal) that we had to remove large clumps from the lower unit of research vessel every couple 100 meters. Estimates of infested areas were made using measurements in Google Earth (canal w x length)- infestation appeared throughout entire canal between S-176 and S-177 water control structures. Estimate does not include large dense mats infested in the western edge of C-113.; EDDMapS report
