A massive lake about two-thirds the size of New York City has developed a luminous green color that looks out of this world.

What is more disturbing are the mysterious green swirls that are evident and so intense that they can be seen from spaceindicates that something dangerous is happening.

And several lakes are affected.

In fact, Pyramid Lake, in northeastern Nevada, is highly toxic due to a phenomenon that occurs almost every year.

POT released photos of the black and green body of water last month, along with similar images of Clear Lake in California (from May) and Lake Erie (in August).

Fortunately, it is not as alarming as you might first think and it has been happening for a very long time.

Naturally, one might imagine that it comes from some kind of sewage or chemical spill, but you would be wrong, although it is still toxic.

It’s just part of a algae bloomytThe only difference this year is that levels of Nodularia spumigena, which is a type of cyanobacteria often found in warm, brackish or saline lakes, are much higher than usual.

It was identified by the Pyramid Lake Paiute Tribe, who frequently monitor algae levels in the lake, and have now warned tourists to avoid taking a dip in the water…although I’m not sure who in their right mind I would like to do it. swim in a bright green lake.

Speech to In the San Francisco Chronicle, the Tribe said, “Bloom material is decomposing and releasing the toxin microcystin into the water, signaling a turn toward normal conditions that may take 2 to 3 weeks to normalize.”

Aaron Bill, water quality manager for the tribe’s natural resources department, has reiterated that sentiment.

He said: “We always want to make sure people are aware of it, so they don’t bring their animals “or they would restrict them and have their own drinking water.”

Yes, water is quite dangerous; in fact, it has caused visitors to suffer from rashes, diarrhea and fatigue.

But that’s not all. When the toxin is inhaled, it can even attack the brain.

When tests were conducted in the San Francisco Estuary, chlorophyll a and cyanobacteria b were found to increase from late September to mid-October.

So if you visit Pyramid Lake anytime soon, be sure to stay away from the water.
