I agree that the culvert would make a great ground ... better than a
Ufer as long as it lasted, at least. If the ground water level is that
high, though, I'd probably worry about the culvert eventually rusting
out. Rebar is cheap enough in comparison to the cost of that much
concrete that I think I'd drop a few 10' long sticks into the pour for a
Ufer anyway. Just connect them to the tower legs as if the culvert
wasn't there. Cheap insurance, in my opinion.

Subject: [TowerTalk] Tower base/Ufer ground
I have a proposal from a contractor to pour the concrete into a piece of
48" diameter x 12' long piece of steel culvert capped on the bottom end with
a plywood disc. Very high ground water is the reason.
Will this constitute a Ufer ground?
