I would think the wet/dry vac empties or nearly empties a pond.

I use a small shop vac to muck out the filter barrels and it fills up
and stops sucking at about 15 gallons. I usually dump and begin
again because the pump in it is so slow. I tried a pump with two
hoses once, but didn't need that much volume and went back to the shop
vac.
