Theere are several logical explanations for this photo
Indeed there's a logical explanation for any omen.
Because everything the LOGOS (= Alpha and Omega) does or allows to happen, is LOGical.
These omen-like pictures (with water turning blood-red) are only reflecting the situation of our present time. The time is extremely ripe for a 2nd Flood (just not with water this time as promised by God, but with fire for example, as Bishop Williamson says).
And these pictures are only reflecting the upcoming things. That's normal. Just take a look at history which always is salvation history, and so it also includes punishments coming from God or allowed by God, and mostly they've been announced by natural spectacles or similar because it's God's nature. As said, our forefathers were very sensible about such omens, because in contrast to our time they knew that God controls everything.
I'm not confining our discussion to just this single photo posted by Ascent, although it speaks a pretty clear language. But I'm observing omen-like natural spectacles for years now. And their number is increasing. Don't you notice it? I'm sure Ascent, Elisabeth, Incredulous, Rowsofvoices, etc are!
We can be sure the pictures will get more intensive the closer we come to the point of the Chastisement including an extremely bloody World War III. Most people won't see it even then because they don't want to.

And He was also saying to the crowds, "When you see a cloud rising in the west, immediately you say, 'A shower is coming,' and so it turns out. And when you see a south wind blowing, you say, 'It will be a hot day,' and it turns out that way. You hypocrites! You know how to analyse the appearance of the earth and the sky, but why do you not analyse this present time?"
