Lake Washington beaches closed May 23-24 for Milfoil treatments

Seattle Parks and Recreation, with permitting from Washington State Dept of Ecology, will be using aquatic herbicides to systemically control aquatic weeds. The goal is to improve water quality by managing the invasive milfoil at Seattle’s freshwater beaches, swim areas, moorages, and high-use recreation sites.

The first treatment is scheduled to happen Wednesday, May 23. All Lake Washington beaches will be closed May 23 and reopen on May 24.

Permitted use of an aquatic herbicide is endorsed by Washington Department of Ecology as a systemic solution to control specific aquatic weeds that impact recreation and water quality. The permit covers the City owned properties on Lake Washington, Bitter Lake and Ship Canals –Lake Union.
