Are you certain it isn't mega - organic molecules like algae that gives the color When lakes eutrify?, it's because of the addition of minerals (P from laundry and dish detergent) that promote

In my summer swing through northern British Columbia I was reminded of
all the brilliantly coloured mountain lakes. These have very little
laundry or dish detergent in them. Its the green ones that really catch
my eye. I've generally assumed BC's green lakes are related to CuO
rather than plant life (possibly nickel or cobalt, but judging from the
mining industry in BC copper seems more likely).

(Incidently, if you are ever invited to a cottage at "Green Lake, BC",
make sure you find out which one its at.)
