Lakes close because of toxic algae every year, especially as temperatures climb in summer. 

Pierce County’s Lake Tapps is the latest example. Authorities warned people not to swim in the northeast part of the lake last week.

In King County, caution signs remain up at Mallard Lake in White Center, where a sample showed toxicity at levels higher than the state’s guidelines advise on July 10.

It’s the height of summer and the forecast is looking very sunny, providing great conditions for water sports on local lakes.

That also means a higher risk of swimmer's itch, which is linked to another feature of summer that many people enjoy: the presence of waterfowl.
