Since the "olden" days when many of the lakes in our wilderness areas were stocked liberally
by air by our F&G Dept. things have changed. Wilderness areas cannot be flown over is the word I've gathered.
Stocking in them now is done pretty much solely by the HiLakes Clubs backpacking them in or by "Mule Train" stocking and is sporadic at best.
Fortunately many of the lakes have spawnable outlets and many others are inhabited with
Brook trout which usually can spawn without running water in pristine lakes.

A good sportsmanship rule in the Alpine water is if the lake/stream seems to be inhabited by numerous,small eager to bite trout, take a few for camp breakfast/dinner. If fishing is slow or of bigger fish only, C&R everything with barbless hooks.
