How much water has Harvey dropped? A lot.
25 Trillion! That’s 25,000,000,000,000. Gallons of water. Here is what 1 gallon of water looks like.
Now take a million of these and dump them from the sky. Then do THAT 25 million more times. It’s truly staggering. It’s literally like a lake of water.
For comparison, I’ve scraped the largest lakes in the US by volume from wikipedia and visualized them below. The data from wikipedia is in cubic kilometers, so I converted 25 trillion gallons to about 94.6 cubic kilometers.
Here is Harvey’s output compared to the Great Lakes. Not that impressive, but the Great Lakes are absolutely massive. (I can see Lake Michigan out my office window and it basically looks like an ocean.)
If we look at some smaller lakes, this starts to get outrageous. 25 trillion gallons of water is more than Lake Pend Oreille, Becharof Lake, and the Great Salt Lake. Like WAY more than the Great Salt Lake. Like almost 5 Great Salt Lakes! (Can that even be right? That must be a mistake.)
