Twin Lakes drained for weed control – ALASKA

Juneau’s Parks and Recreation Department and the Alaska Department of Fish & Game are draining Twin Lakes to control milfoil. The lakes are drained annually and filled with salt water which controls milfoil without using herbicides. The lakes are to be refilled by mid-April.
