Fife Creek has no individual line in the Region 4 synopsis, but its confluence sits inside the reach of the Whatshan River the province closes above Whatshan Lake ("No Fishing upstream of Whatshan Lake"). The table doesn't say whether that closure extends to tributaries, but given Fife Creek is a documented bull trout spawning and rearing system, treat it as closed until the regional office confirms otherwise. Whatshan Lake itself protects bull trout under 60 cm.

Fife Creek runs about 14 km (stream order 5, well down the network toward river scale) off the Monashee Range, joining the Upper Whatshan River roughly 200 m below the point a 2014 Freshwater Fisheries Society of BC / Columbia Basin Fish & Wildlife Compensation Program kokanee-spawner survey used as its starting transect, itself just above Whatshan Reservoir. That survey found Fife Creek dominated by boulder and cobble substrate, with gradient exceeding 2% in the first 500 m and steepening past 5% beyond that, calling it a known bull trout spawning and rearing system and poor kokanee water: fewer than 200 spawning kokanee turned up in the creek against a peak count of roughly 12,000 on the Upper Whatshan River mainstem that September. Fife Creek supplies most of the discharge feeding the Upper Whatshan River above the reservoir, and a small barrier about 4.5 km up the mainstem blocks kokanee from otherwise-suitable spawning habitat further upstream, though the survey doesn't specify whether that barrier sits on Fife Creek itself or on the mainstem above the confluence.

Provincial fish and stream inventory data records a direct catch of bull trout in Fife Creek, consistent with its documented role as a spawning and rearing tributary for the Whatshan Reservoir bull trout population. No other species has a confirmed record here.

The 2014 survey also measured angler effort on the wider Whatshan Reservoir that year and found it poor: under 3,000 rod-hours from May to September, with virtually no kokanee and only a few rainbow or bull trout landed. Combine that with Fife Creek's likely-closed status, its mouth sits inside the Whatshan River's above-lake fishing closure, and there's no honest case for fishing this creek itself today. Its value is as a nursery, not a destination: bull trout run up from Whatshan Reservoir to spawn here, so treat Fife Creek as a look-don't-fish tributary. Where bull trout streamer fishing is legal and appropriate elsewhere on the Whatshan system, a small Woolly Bugger or Muddler Minnow covers them; see streamer fishing for bull trout.

Fife Creek is reached via the Upper Whatshan and Fife Creek Forest Service Roads: the survey team above used this route to reach its start point, and it's also described as accessible from Whatshan Lake Road across a Whatshan River bridge near Stevens Pass. No named trailhead or parking area specific to angling has surfaced, and no guide coverage exists for this creek.
