0001139: Plant grows in 7/7 water, blocks pump
Pumping from the underground lake had the pump draw up 7 water units making the square dry and either uncovering a fully matured underground tree or allowing one to grow instantly causing the water flows to stop and the pump to fail.

Basically a tree grew in deep water and blocked a pump.
I had drawn water from this spot earlier and then stopped it. When I restarted it the tree appeared. I do not know the tree was there before starting the pump.
No tags attached.

Likely the sapling spawned when you started pumping the first time. They might not be respecting water levels for killing saplings.

Supposedly they can grow in 7/7 water anyway -- see 0000457

There was a tag back in 40D that let you set the depth of water that would kill saplings, maybe that could be it?

If the pump is working continually then the square it is pumping from may be mostly 1/7 not 7/7.
