What does pink water in a lake/pond indicate? I saw this on a documentary

[raccoon]

but if they said what caused it, I missed it.

1. You mean like in South America?

There's a huge lake in Bolivia which is pink-colored. It has to do with certain minerals. Salt is one element that will discolor liquids.

2. Red algae? There is a lake in Australia that looks pink.

3. I think in the film it was supposed to be something that was a bad sign.

I thought, methane? But chemistry isn't my strong suit.

12. lake in texas just turned red

A Texas lake that turned blood-red this summer may not be a sign of the End Times, but probably is the end of a popular fishing and recreation spot.

A drought has left the OC Fisher Reservoir in San Angelo State Park in West Texas almost entirely dry. The water that is left is stagnant, full of dead fish — and a deep, opaque red.

The color has some apocalypse believers suggesting that OC Fisher is an early sign of the end of the world, but Texas Parks and Wildlife Inland Fisheries officials say the bloody look is the result of Chromatiaceae bacteria, which thrive in oxygen-deprived water.

13. Sign of the Apocalypse...

Revelation 16:1-4 “The second angel poured out his bowl on the sea, and it became as the blood of a dead man, and every living soul died in the sea. The third angel poured out his bowl upon the rivers and the fountains of water, and they became blood.”
