As summer approaches, so does the potential for algal blooms across temperate zone lakes. This phenomenon can be a common problem for lake visitors and residents looking to enjoy a day out on the water. These blooms can start to occur as temperatures increase and excess nutrient loads enter the waterbody. Lakes that exhibit tendencies towards higher productivity are known as eutrophic, and can be great environments for blue-green algae growth. This growth can be a nuisance to recreationalists if widespread, and can sometimes be toxic. In a report by KPLU (NPR) Lake Lorene is being treated with a new product to lock up excess phosphorous nutrients in order to prevent future blooms. The product is being used under an experimental permit by the Washington Department of Ecology. For more information on blooms visit the Washington Department of Health & Oregon Health Authority.
