Wilmer Creek flows east into the Columbia River just north of Windermere Lake, close to the small community of Wilmer and a short drive from Invermere. It carries a surprisingly strong local record count for a creek this size: local beat data logs 76 direct fish observations here, led by rainbow trout (41) and brook trout (26), with redside shiner, longnose dace, northern pikeminnow, largemouth bass and other small fish rounding out the lower-food-web mix.
The water
BC Geographical Names lists Wilmer Creek as an official watercourse draining east into the Columbia River. It runs stream order 3 (a small-to-mid tributary, on a scale that runs from 1 for a headwater trickle up to 6 or more for a full river) and stretches roughly 16 km. Channel-geometry data puts it firmly in small-creek territory: a median width of about 3.2 m (narrow), a median gradient of about 0.41% (very gentle), and a peak mean-annual discharge of about 0.056 m³/s (very low flow). That is a gentle, low-volume creek rather than a driftable river, consistent with the tight, pocket-water character local anglers describe.
Water Survey of Canada runs a hydrometric station on the creek itself, Wilmer Creek near Wilmer (station 08NA057), so flow context is available before you plan a trip. The creek sits close to, but is a separate feature from, Wilmer Lake a few kilometres to the southwest, a stocked brook trout stillwater with its own record.
The fishing
No dedicated habitat assessment or guide report on Wilmer Creek turned up, so this reads as a fish-record-backed scout water rather than a documented destination. Where access is legal and flows run cool and clear, the gentle gradient and narrow channel suit quick, cover-to-cover fishing: short drifts with a dry/dropper rig, and a small streamer worked through the deeper cuts and undercut banks.
Expect the same summer hatches common across Columbia Valley tributaries: Mayflies, Caddisflies (Sedges), small Stoneflies and summer Terrestrials (Hoppers, Ants, Beetles), with redside shiner, dace fry and other Baitfish & Fry filling out the forage base. A light attractor box covers most of the water: Stimulator, Royal Wulff and Adams on top, backed by an Elk Hair Caddis, Hare's Ear, Prince Nymph and Pheasant Tail below, with a small Woolly Bugger for the deeper cover.

Access and the rules
No named trailhead, parking area or confirmed public access point has turned up for Wilmer Creek, and it isn't clear whether the lower creek crosses private or posted land. Kootenay Troutfitters is the nearest Columbia Valley guide outfit, but no source confirms dedicated Wilmer Creek guiding. Treat this as a regulation-and-access check before you go rather than a mapped-out day trip.
Before you fish
Conditions & stocking
- Navigability: a narrow, low-volume creek (median width ~3.2 m, narrow; median gradient ~0.41%, very gentle; peak mean-annual discharge ~0.056 m³/s, very low flow), consistent with the tight pocket water anglers describe rather than open drift water.
- Stocking: no stocking record. Wilmer Creek runs entirely on wild fish, unlike nearby stocked Wilmer Lake.
