Ecology Department approves milfoil treatment
Friday, September 9, 2011
SPOKANE, Wash. (AP) -- The Washington Department of Ecology has approved a plan that sharply reduces the amount of Lake Osoyoos that will be treated with chemicals to control milfoil.
The agency approved the Okanogan Noxious Weed Control Board's plan to treat milfoil in approximately 10 acres of isolated coves in the Washington portion of the lake, in response to concerns raised by British Columbia officials over original plans to treat 300 acres.
The agency said it is confident that the lake treatments will protect water quality, and it believes treated water will not enter the British Columbia portion of the central Washington lake.
Milfoil is a non-native, invasive plant that forms dense mats of vegetation on the surface of lakes, interfering with swimming, fishing, water skiing, and boating.
