No Geary Creek-specific exception is listed in the checked Region 4 extraction, so default Region 4 stream rules apply: closed Apr 1 to Jun 14, trout and char catch-and-release Nov 1 to Mar 31, single barbless hook year-round. Region 4's Columbia Lake table (4-25) closes fishing on the lake's tributaries entirely except Dutch Creek. BC Geographical Names maps Geary as flowing into the Columbia River just north of the lake rather than into the lake itself, but confirm that distinction against the current synopsis before you fish, since a Columbia Lake tributary closure would override the stream default. Avoid fishing over visible spawning kokanee in any case.

Geary Creek's mouth sits at 50.31278, -115.85611. No channel-geometry survey (stream order, width, gradient, discharge) has been logged for the creek, so treat it as a small, unmeasured tributary until that data turns up. The local fish-record model carries exactly one direct observation for the creek: a kokanee. There is no broader trout observation on file, which is a thin signal even by small-tributary standards.

With a single kokanee record and no documented trout population, Geary is not a fishery to build a trip around. The honest read is spawning-corridor caution: kokanee use lower Columbia Valley tributaries like this one to spawn, so stay off redds and do not target visible spawning fish. If a non-spawning reach turns out to have legal access, fish presence and cool perennial flow, small, sparse patterns suit the water.

If access, fish presence and cool flows are confirmed on a non-spawning reach, small patterns match the water: Adams, Royal Wulff, Elk Hair Caddis, a small Stimulator, Hare's Ear, Prince Nymph and Pheasant Tail. Any lower, river-connected water may also hold kokanee fry and other baitfish and fry worth a small streamer, well away from spawning fish.

Likely forage on the lower, river-connected water includes small mayflies, caddisflies, small stoneflies and summer terrestrials, alongside kokanee fry and other baitfish and fry, consistent with a small Columbia Valley tributary tied into the river's forage base.

No named trailhead, landmark or confirmed public access point has turned up for Geary Creek, and legal access has not been verified. Kootenay Troutfitters is the nearest Columbia Valley guide outfit, but no source confirms dedicated Geary Creek guiding.
