Mountain lakes are completely different.
There’s fish eggs being washed everywhere during rain storms. The eggs come from upstream and wash into random places.

But I always thought the explanation was eggs randomly getting stuck to bird feet. Or maybe a bird carries a fish with eggs up there and eats it or something. Inevitably it happens though...

Is it unbelievable that ancient hunter-gatherers would do the same thing?
This looks like a good overview paper for interested folk: https://pmc.ncbi.nlm.nih.gov/articles/PMC3048989/
Many do have rivers; many don't. Ponds even more so don't have attached rivers.
Alpine lakes are fed by snow met. There’s not going to be fish eggs on the snowpack that melts into the lake.

Do you realize that in the summer mountains below 4000m are mostly snow-free and thawing point ie in Europe has been pushed above 5000m repeatedly during summers. Its easy to have 25C in 2500m in today's alps (ie today 22C in 2000m in Chamonix, France).
The term 'alpine lake' doesn't mean anything specific, and most are fed from rain during entire summer without any/much of snow or ice contribution.
If hunter gatherers did it 7000 years ago, should be possible to suspect it, but modern people do this things all the time. It should be easier to prove at least that they not were released in, lets say, 1780.
