For an angler judging whether the drive is worth it, the stocking record is the fishing report. Fenwick Lake is a put-and-take
rainbow trout fishery: 42 of the 45 recorded releases (60,334 fish) were rainbow trout, most recently 750 Pennask-strain yearlings on 2026-05-20, averaging about 5 g at release. A shorter run of
westslope cutthroat trout went in three times in the early-to-mid 2000s (2002, 2004 and 2006, fall fry, 3,000 fish total, Connor strain) but has not been repeated since; today's program is rainbow-only.
That near-continuous run since 1957, through several hatchery strains (Beaver, Gerrard, Niskonlith, Premier and now Pennask) before settling on today's Pennask yearlings, makes Fenwick a genuine put-grow water: last year's plant is this year's fish, refreshed on close to an annual cycle. The chart above shows the full release history by year and species.
