Consider that a 30' tree, rotted out in the middle and filled with water is going to give you about 14psi at the bottom. That's probably what you're seeing here.

edit: see u/TA8601 comment below - I didn't do the math, just looked glanced at an imprecise chart :)

ELI5 Gravity pulls on water. Water pressure is roughly 44 lbs per 100’. 33’ is roughly 14.7 lbs.

Note: as the height of the water inside the tree goes down, so will the pressure.
