Lake Goodwin

Lake Goodwin is one of a group of seven lakes just north of the Tulalip Reservation in Snohomish County that are regularly sampled by IWS (Crabapple, Goodwin, Howard, Ki, Loma, Martha, and Shoecraft). Lake Goodwin is the largest lake in this group (535 acres), with an average depth of 23 ft. The lake became infected with Eurasian watermilfoil in the 90s. A series of removal and barrier projects have been instituted to help keep the invasive plant at bay.
