Newman Lake Access Closes on June 24-25
for Aquatic Weed Control
SPOKANE COUNTY, June 18, 2020 - The Washington Department of Fish and Wildlife (WDFW) public access site at Newman Lake in eastern Spokane County will be closed June 24-25 for treatment of the lake with herbicide to control Eurasian milfoil and other invasive aquatic weeds.
The Newman Lake Flood Control Zone District, under permit from the Washington Department of Ecology, has hired Aquatic Weed Solutions to treat milfoil infestations on about 60 acres throughout the 1,200-acre lake with 2-4-D Amine, (dichlorophenoxyacetic acid, dimethylamine salt).
A swimming restriction will be in force during the entire day of treatment, and for 24 hours after treatment. Boating and fishing will be discouraged the day of treatment and for one day after. Irrigation and household use of water pulled from the lake should be discontinued for up to seven days following treatment. Mailed notices have been sent to shoreline residents, and signs with that information will be posted. The boating restriction is needed because wave action reduces the herbicide’s effectiveness.
Aquatic herbicide application permits authorized by Ecology include requirements and restrictions to protect fish and wildlife.
WDFW access manager, Daniel Dziekan, said the gates to the area will be closed early on Wednesday, June 24, and re-opened early on Friday, June 26.
Newman Lake is about 20-miles northeast of Spokane, about two miles west of the Idaho border, and is open year-round for fishing.
