Green Algae?

I walked round the lake yesterday & saw these birds, I called the park security who said they were aware of it & that someone was to come & do further tests. The lake hadn't been closed off last night, not sure about now. Shouldn't they get the rest of the birds out? http://www.manchestereveningnews.co.uk/news/greater-manchester-news/dead-birds-boggart-hole-clough-7471929
