Gainer Creek drains the east side of the Lardeau Creek valley toward Trout Lake, in the Ferguson mining country north of Kootenay Lake. Provincial geological mapping treats it as one of the larger streams in the map area, alongside Lardeau and Ferguson creeks, but no fisheries survey has logged a fish directly from Gainer itself. Read it as a habitat and access scout rather than a proven fly-fishing destination.
The water
NRCan's Geographical Names database lists Gainer Creek as an official Kootenay Land District name at 50.661944, -117.348889. It runs stream order 4 (mid-range on a scale that runs from 1 for a headwater trickle up to 6 or more for a full river) and stretches roughly 11 km before joining Lardeau Creek. BC Geological Survey Bulletin 45 groups Gainer with Lardeau and Ferguson creeks as the largest streams draining the Ferguson map sheet, cutting steep valleys between high peaks on their way down to Trout Lake.
The fishing
The local fish-record extraction found zero direct observations on Gainer Creek. What it inherits is an inferred sportfish context from the wider Lardeau system, where bull trout are the known, conservation-sensitive species. That inference is a working hypothesis, not a catch record, and it should not be read as a promise of fish in this specific drainage. Confirm fish passage, gradient and lower-reach access before planning a trip around it.
If a legal, fish-bearing reach turns up, small attractor and searching patterns fit high-country scout water: Stimulator, Elk Hair Caddis, Adams, Royal Wulff, Prince Nymph, Hare's Ear, Pheasant Tail and a small Woolly Bugger-style streamer for any sculpin or juvenile-fish water. Likely food, if a lower reach proves fish-bearing, follows the small-stream pattern of the wider valley: Mayflies, Caddisflies (Sedges), Stoneflies, summer Terrestrials (Hoppers, Ants, Beetles), tiny Sculpin and juvenile fish.
Scout water, not a destination

Conditions & stocking
- Navigability: no bcfishpass channel-geometry record (width, gradient, discharge) exists for Gainer Creek. Stream order 4 and the surrounding steep, high-country terrain point to a small, technical tributary rather than driftable water.
- Stocking: no FFSBC stocking record. Any fish present would be wild.
Access and the rules
No named trailhead, parking area or confirmed public access point has turned up for Gainer Creek. The Ferguson mining country it drains carries old roads and workings tied to the Mohican and Index-area prospects, so plan any visit as backcountry routefinding and confirm land tenure before you go. No guide coverage of Gainer Creek was found.
