For an angler judging whether the rainbow side of the lake is worth the drive, the release record backs it up: 126 recorded stockings totalling roughly 1,030,000 fish since 1929. The modern program is Blackwater-strain rainbow trout only, typically 6,000 to 10,000 yearlings released every fall between September and November, sourced from the Kootenay Trout Hatchery near
Premier Lake and the Dragon Lake Hatchery. The most recent release, on 2025-10-24, put in 10,408 rainbow averaging about 50 g. Brook trout were part of the historical program too, three releases totalling 36,000 fish, but none since 1970: the lake today is a rainbow-and-bass fishery, not a brook trout one. The full year-by-year release history is below.
