What makes the water in BSR Cable Park in Waco so green? The water is this color in most of their basins, I'm unsure if it's fed by natural springs or if it's all man made. Is the green water dangerous?
As far as I'm aware water this color usually means there is a bad algae in the water that can make you sick. Yet there are so many people swimming in these waters. Do we need to watch out when accidentally swallowing water or something?
They dye it to cover the color the soil it's built on would usually give the water:
"If there’s any drawback to BSR it’s that, because all the water attractions are man-made and dug into the clay soil of central Texas, the water would normally be an unpleasant gray color. So they dye it, either an unnaturally garish turquoise or a drab olive green."
