Dunaliella salina dominates the algae in the lake and this species produces beta-carotene in such large quantity that the water becomes quite red in color.
Contributing somewhat to the red color of the north arm is the presence of Halobacterium, a bacterial species that accumulates a rhodopsin-type of pigment.
yep, thats algae alright
