For an angler judging whether a lake like this still holds fish, the release record is the best evidence on file. Snowshoe Lake was stocked with
rainbow trout 28 times between 1926 and 1988, roughly 121,000 fish in total, drawing on hatchery strains that shifted over the decades: 20,000 Gerrard Creek-strain eyed eggs in the first recorded plant in 1926, followed by Spahomin Lake, Knouff, Beaver, Badger, Dragon and finally Pennask-strain fish by the 1980s. The last recorded release, on 1988-10-01, put 2,000 Pennask-strain rainbow trout into the lake, and nothing has been stocked since.
That near-four-decade gap since the last plant means Snowshoe Lake cannot be treated as an active put-grow fishery today. If rainbow trout persist, they are either a naturally sustaining population or a low-density holdover from descendants of the 1988 plant; confirm the current state locally before counting on this water.
