Newman Lake access to close June 7 - 9
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 June 7 - 9 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 30 acres throughout the 1,200-acre lake with 2-4-D (dichlorophenoxyacetic acid, dimethylamine salt).   

A swimming restriction will be in force during treatment and for 24 hours after treatment.  Boating and swimming will be discouraged the day of treatment and for two days after.  Signs with that information will be posted. The boating restriction is needed because wave action reduces the herbicide's effectiveness.

Karen Kruger, Spokane County Water Resources Technician, says the past three summers of aquatic weed treatments at Newman Lake have reduced the original infestation tremendously, thanks in part to volunteer efforts to help keep boaters out of the herbicide application areas.

Aquatic herbicide application permits authorized by Ecology include requirements and restrictions to protect fish and wildlife.

WDFW access manager Daniel Dziekan says the gates to the area will be closed early on Tuesday, June 7, and re-opened early on Friday, June 10.

Newman Lake is about 20 miles northeast of Spokane, about two miles west of the Idaho border, and is open year-round for fishing.
