My nerdy civil engineers guess: the river bank has overflowed and a secondary berm is near top. A backup culvert pipe is draining below which will cause a whirlpool above. Functioning, but STAY AWAY!
It looks like an over flow valve was opened. It’s just pumping excess water out so it doesn’t flood. That’s probably why the geese aren’t near it but also aren’t spooked by it. Their used to it.
Sometimes the suction isn’t even caused by a pump house rather a pipe is manually or automatically opened and physics take over. This is all common stuff and basic physics.
