Yes, it appears to be fixed. Sadly, the solution involved no midnight elephants or spacetime rifts.
The flexible pipe between the pump and waterfall had an intermittent leak. Why intermittent? I don’t know. I dug it up and watched a few weeks and found no damp ground. But then it sprayed me when it flexed as I repositioned it. Maybe it varied with the sprinkler schedule, leaking less into saturated soil, or temperature, expanding and contracting — one of the world’s great mysteries.

In the course of finding the leak, I’ve rebuilt the waterfall, taken apart and re-sealed the pump housing, completely drained the water to clean and check the liner for punctures, removed all landscaping to clean and re-level the liner edge, and removed watercourse rocks to re-seal a seam there. The last two I actually did twice.
… which is all to say that pond ownership may require a love of puzzles, digging and futility.

It will be another season or two before plants fill in everywhere I had to dig.

Some remember we once had larger fish, a foot or more in length. That was before the Dark Ages, when aquatic life was beset with such pestilence as grade school boys, a hard freeze, a faulty pump and, of course, The Leak.
