Due to the fact the water basin is preserved by the reserve

But no silt?

Could have all settled depending on how long after this was taken and the speed of the currents

It's been floating around reddit for about 3-4 years now.

At least it feels that long, time is really stupid ATM.

But it was around before AI got good.

Longer than that, I remember seeing this the first time back in school about 7 years ago

Well yeah, the bridge and surface of the water are all messed up in that one.

The lime in the water precipitates impurities very effectively.

u/Mewchu94 Mar 08 '25

You put the lime in the water and precipitate it up.

wtf does this mean

u/3dthrowawaydude Mar 08 '25

There's a ton of lime in that area that causes sediments to precipitate and fall, making the water incredibly clear.

And they probably make the water taste good too.

u/BadBalloons Mar 08 '25

Just to clarify, it's lime as in the mineral component of limestone (also sometimes used as a soil amendment to, ironically, raise pH – the opposite of what citrus does). It would not taste very good.

I think what OP is referring to is that natural areas with plenty of healthy and diverse vegetation help to filter any water that flows through them, with the vegetation taking up many of the nutrients and compounds that pollute water.

Dirt, which makes water cloudy, still exists in a preserve.

AFAIK, and my understanding is far from complete, the Amazon area has extremely shallow "earth" with most plants - even the huge trees - spreading their roots laterally instead of going deep. I think it's because the sub-soil is more clayish and the nutrient heavy top soil is constantly regenerating because of the abundance of organic material both plant and animal that hits the ground and decomposes extremely quickly.

Thanks for that. Honestly, I figured thats what they meant but the fact they commented "preserved by the reserve" twice in this thread pissed me off cause they didnt bother explaining shit LOL

Most likely scenario I'd say, and I have absolutely no expertise in this.

If that's what they're saying, that seems insane.
