Newman Lake access to close Sept. 9-11
for aquatic weed control
The Washington Department of Fish and Wildlife (WDFW) public access site at Newman Lake in eastern Spokane County will be closed Sept. 9-11 to allow treatment of the lake with herbicide to control Eurasian milfoil and other aquatic invasive weeds.
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.
Karen Kruger, Spokane County Water Resources Technician, says the June aquatic weed treatment at Newman Lake went well, thanks in part to volunteer efforts to help keep boaters out of the herbicide application area.
Aquatic herbicide application permits authorized by Ecology include requirements and restrictions to protect fish and wildlife.
WDFW Eastern Region access manager Scott Young said the gates to the area will be closed early on Tuesday, Sept. 9, and re-opened early on Friday, Sept. 12.
Newman Lake is about 20 miles northeast of Spokane, about two miles west of the Idaho border, and is open year-round for fishing.
