Weed Harvesting


Below is a brief list of the weeds of concern in DeRuyter Reservoir. Currently, June 22, 2017, harvesting began on the south end to remove mainly Curly-leaved pondweed. If available, we’ll try to update this site with an estimate of the amount of wet tonnage removed.


Much of this information was copied from Cornell University Invasive Weed ID Guide
