With regards to the pond, if it wasn't possible to gley I would look at other options such as a series of small ponds from old baths etc.
I'd probably plan around it in the future, but would focus on getting trees established first

As far as pond liners go, what's wrong with plaster? All natural earth elements.

Do ponds develop their own liner eventually with sedimentary deposition? I wonder if a biodegradable plastic could be used to start the pond that will eventually break down when it is no longer needed.
I'm fairly sure there is no such thing as biodegradable plastic.
Yes, I know we can make plastics from plants. I'm just not sure they fit the definition of 'biodegradable' that I use. There are hard cornstarch containers that when wet go soft, and these compost fine. But I've not seen a 'plastic' bag or pottle that biodegrades naturally and easily.
If we're not going to buy in compost as a design principle, why are we buying in pondliners?
H Ludi Tyler is in a tough situation. S/he needs a good solution to retain water during a mega drought and needs it immediately. If and when a good rain comes it would be best to be prepared for it. For now I would be looking at liners as effective short term solutions while we permies develop or create better long term solutions.
