The swimming areas at Meydenbauer and Newcastle beach parks will be closed next week as a precaution while nearby property owners apply herbicide to control invasive milfoil blooms. 

Although swimming will be off-limits at Meydenbauer Beach Park (419 98th Ave. NE) on Monday, July 18, and Newcastle Beach Park (4400 Lake Washington Blvd. SE) on Tuesday, July 19, the parks will remain open.

According to the state Department of Ecology, milfoil, which grows in dense mats near the shoreline, can drastically alter a water body's ecology and trap sediments.

Signs will be posted on-site regarding the 24-hour swimming area closures. For questions about the milfoil treatment, call Rick Bailey at 425-452-6031. Parks & Community Services (425-452-6885) offers information about all of the city's parks as well as other programs and services.
