Lake Wendouree.

Some of the prettiest algae I've seen. Also, it's really this hazy - the temperatures are in the upper 90s with humidity upwards of 80%, so visibility is about a mile.

Algal blooms, which can occur in nutrient-enriched waters, cause thick, green muck that pollutes the water and can be harmful to aquatic life, the environment, and to the economy. Some algal blooms produce toxins that are dangerous to people. People should avoid contact with waters that have harmful algal bloom advisories posted or anywhere the water is pea green, discolored, or has floating mats.

Bryopsis Algae Seagrass Shallows PR03a

Xavi points out the only part of Algae Lake that they are not allowed to swim in. If they get too close to the aerator, they might break it and then Algae Lake would become completely overrun by green guck.
