BOATING --The public access site and boat lauch at Newman Lake will be closed Sept. 9-11 to allow treatment of the lake with herbicide to control Eurasian milfoil and other aquatic invasive weeds.

The Washington Department of Fish and Wildlife says gates to the access at the Spokane County lake will be closed early on Tuesday, Sept. 9, and re-opened early on Friday, Sept. 12.

The Newman Lake Flood Control Zone District, under permit from the Washington Department of Ecology, has hired Aqua Technex to treat milfoil infestations on about 28  acres throughout the 1,200-acre lake with 2-4-D (dichlorophenoxyacetic acid, dimethylamine salt), Diquat, and Glyphosate.  The treatment is a follow-up to similar work conducted in June.

A swimming and boating restriction, noted on posted signs, will be in force during treatment and for 24 hours after treatment. The boating restriction is needed because wave action reduces the herbicide’s effectiveness.

Newman Lake is open to fishing year-round.
