The swimming areas at Meydenbauer, Clyde and Newcastle beach parks will be closed for one day next week as a precaution while nearby property owners apply herbicide to control invasive milfoil blooms. Though the swimming areas will be closed, the parks will remain open.

On Monday, July 16, swimming will be off-limits at Meydenbauer Beach Park (419 98th Ave. NE) and Clyde Beach Park (9415 Lake Washington Blvd.); on Tuesday, July 17, the swimming area at Newcastle Beach Park (4400 Lake Washington Blvd. SE) will be closed. 

According to the state Department of Ecology, milfoil is considered the most problematic plant in Washington. Milfoil can drastically alter a water body's ecology and rob oxygen from the water by preventing the wind from mixing the oxygenated surface waters to deeper water. The dense mats of vegetation can also trap sediments.

Signs will be posted on-site regarding the swimming area closures. For questions about the milfoil treatment, call Rick Bailey at 425-452-6031.
