I have seen rivers and lakes turn green, If my memory serves me correctly, and I may be wrong ok, as for a lake this happens when the water turns
over. and water does turn over in lakes about once a year. I saw this at Lake Isabella in californias kern county a few times. and as for rivers i was
told this happens when the rivers water level get higher, infact here in montana I am watching the missouri river turn green, its called algie
surficing itself.
