Feat in question:

My rage exploded.
And so did the river. It blasted away from me in every direction, putting me at ground zero of the detonation—curled up alone in a bubble of air, howling so loudly I could hear myself even over the roar of the torrent. Some part of me had reached outward . . . not just into the pool, but to the source of the river, deep down in the Underworld or maybe Yonkers, and I had pulled it up by its roots. Millions of metric tons of water roared through the cavern, flooding the pool, scouring the cliffs, surging over the river banks, and probably surprising a whole bunch of snakes bathing downstream. At last, the water crashed back around me, settling into its normal flow again
Character is controlling pretty much the entirety of the Elisson/The Saw Mill River. I thought it would be a KE calc but the speed is kinda ambiguous here.

Very rough attempt at a calc

Lowball speed & super lowball mass (assuming 2 million metric tons of water and speed of a fast stream): (6.71^2 m/s)(2x10^9 kg)(1/2)=4.50241x10^10 (Large Building Level)

Lowball speed and mid mass (assuming 10 million metric tons of water and speed of a fast stream): (6.71^2 m/s)(1x10^10 kg)(1/2)=2.251205x10^11 (City Block Level)

Lowball speed and highball mass (assuming 20 million metric tons of water and speed of a fast stream): (6.71^2 m/s)(2x10^10 kg)(1/2)=4.50241x10^11 (Multi City Block Level)

Now, regarding the speed of the water, the current value (speed of the fast river) is a huge lowball. Percy has been making water go faster than that since the first series, and this is a more experienced Percy exerting his full strength.

“I ran toward them, jumping past duels, weaving between the legs of giants. The nearest water was the creek, half a mile away...but I had to do something. I concentrated. There was a pull in my gut, a roar in my ears. Then a wall of water came rushing through the trees. It doused the fire, Juniper, Grover, and pretty much everything else.” (Battle of the Labyrinth)

Percy pulls water from half a mile away in just a few seconds. He’s standing in the middle of an active battlefield so not much time to stand and concentrate, I’ll say around 5 seconds so a speed of 160.935 m/s. This seems appropriate to use in this case since he’s both fully exerting himself and utilizing the rivers pressure to move it.

Now, redoing the calcs with this value.

Appropriate & super lowball mass (assuming 2 million metric tons of water and aforementioned speed): (160.935^2 m/s)(2x10^9 kg)(1/2)= 2.59000742x10^13 (Town Level)

Appropriate speed and mid mass (assuming 10 million metric tons of water and aforementioned speed): (160.935^2 m/s)(1x10^10 kg)(1/2)=1.29500371x10^14 (Town Level)

Appropriate speed and highball mass (assuming 20 million metric tons of water and aforementioned speed): (160.935^2 m/s)(2x10^10 kg)(1/2)=2.59000742x10^14 (Town Level)

To me, the appropriate speed and mid mass calc seems like the best. But like I mentioned before, I suck at calcing, so take all this with a grain of salt.
 
That I'm interested in
There's a glaring lack of LS feats in the verse without scaling everybody and their mother (or father in most cases) to "Lifting the sky"
 
Wait whats he scaling to?

Wouldn’t it be LS with his powers not just his standard LS?
😭
Attack Potency: City level (Comparable to Jason Grace, who could create a storm powerful enough to contain Gaea; can also create storms as a side-effect of his powers as well. Caused substantial damage to Hubbard Glacier. Triggered the volcanic eruption of Mount Saint Helens, which is said to release about 24 megatons of energy. Fought beings like Kronos, Hyperion and Giants. As one of the big three demigod children, he should be comparable to Hazel Levesque, who was able to destroy a small island. Fought Jason Grace and briefly took him down, though it should be noted that the latter did the same too. Fought Luke Castellan, who is the most skilled swordsman in 300 years in Camp Half-Blood), higher when submerged in water, with the Curse of Achilles (Fought the likes of Hades, Hyperion, and a possessed Luke Castellan), or when hosting Nekhbet (Tackled Setne), can ignore durability against supernatural beings to an extent with his Celestial Bronze Sword
 
Saw one of the guys working on the future revisions say that that Jason storm calc was done wrong and would probably have to be scrapped. Then the Hubbard Glacier feat which is in the same tier as this one. The Mt St Helens feat is there but it’s more of a dura feat than anything since Percy only set off the eruption. Hazel feat is Large Town Level.

Overall, anything town-large town level is pretty consistent for the high tier demigods, though I don’t mind the city level rating

there's a way we can go about this that is more accurate and doesnt't require making as much assumptions of volume as what you have here, river has length of 37.8 km and the its average depth is actually less than 1m (average width varies from 3m ~ 8m).
Density of Water: 1000 kg/m3
River Flow Speed During Floods: 25kmph or 6.94444m/s^2

Version 1:
We'll just use what we have here and calculate the volume as if it were rectangular in shape which is pretty simple itself
37800m * ((3+8)/2) * 1m = 207900m^3

207900m^3 * 1000 kg/m3 = 207900000kg or 207900 Metric Tons of Water
0.5 * 207900000 * 6.94444^2 = 5013014416.67 Joules or 1.19814 Tons of TNT (Building level)

This would likely be most accurate considering this river isn't very wide or deep at all but going by the book the best we could do is assume 2 million metric tons as we have no real reason to assume the volume would jump nearly as high as you have it here considering what the more accurate assessment of I have done got.

Version 2"
0.5 *2000000000 * 6.94444^2 = 48225246913.6 Joules or 11.52611063900574 Tons of TNT (City Block level)


As you have pointed out though the ALL of the water in the river arrives pretty quickly and the speed you calculated would be accurate so once again using that here for these two ends

Low End:
0.5 * 207900000 * 160.935^2 = 2.6923127e+12 Joules or 643.4782 Tons of TNT (Multi-City Block level)

High End:
0.5 * 2000000000* 160.935^2 = 2.5900074e+13 Joules or 6.1902663 Kilotons of TNT (Town level)

overall either of these two revised ends here would be more accurate so actually taking the statement over our own calculated volume would make the 6.19 Kiloton value the most viable here

Yeah, definitely think using the 2 million metric tons value with the speed I calced is the best option here considering the text vaguely implies he's pulling the river up from the Underworld (this would make the volume way higher but it's too vague to use anyways.

High end with the corrected speed seems good, appreciate the help 🙏🏽
 
if you goon hard enough you can reach 5B values but I think it should calc to way higher than what he is right now since he's afraid it can wash annabeth away to very distant oceans
5B 😭 Yeah ik of the Atlantic statement but sadly it's too ambiguous and vague to even try calcing for so I had to lowball
 
oi
what atlantic statement
mind dropping it?
I was trembling, strung out, and terrified by what I'd done. I don't know how long it took me to regain my senses. Seconds? Minutes? As the silt cleared, I looked up and had one clear thought: Annabeth. If I had accidentally washed her into the Atlantic, I would never forgive myself.
I shot to the surface.
I shouldn't have worried. On the ledge above, Annabeth sat with her ankles crossed, talking calmly with a very rattled Elisson.
Like I said, can’t really get anything out of it.
Anything saying the type of river?
All I know is it’s the irl Saw Mill River https://en.m.wikipedia.org/wiki/Saw_Mill_River
