No individual Pat Creek entry appears in the Region 4 synopsis. Handle it as an Upper Duncan / Duncan Lake tributary: streams close Apr 1 to Jun 14, trout and char run catch-and-release in streams from Nov 1 to Mar 31, single barbless hooks are required in all Region 4 streams, and Duncan Lake's tributaries (4-27) carry a bull trout release rule. Do not apply Duncan River mainstem exemptions, quotas or bait wording to this creek unless the official table or Region 4 staff confirms it. Confirm the current synopsis before fishing.

NRCan's Geographical Names registry places Pat Creek's mouth at 50.525, -116.970556 (key JBCRS); a second, unrelated Kootenay Land District Pat Creek sits far to the north and is not this water. It runs stream order 3 (low on a scale from 1 for a headwater trickle up to 6 or more for a full river) and stretches roughly 3 km down to the reservoir. Provincial fish-inventory data carries no direct records on the named creek line, only a broader 19-taxa Duncan Reservoir-edge watershed context shared with Idaho Creek next door.

With no direct fish observations, no creek-specific guide coverage and no fishing or hatch reports turned up, there is nothing here to recommend as a destination yet. Reel Adventures Fishing Charters covers Duncan Lake at the lake and charter level, not this creek. Pat sits in the same reservoir-edge watershed context as Idaho Creek, and near Clancy Creek (direct rainbow trout records) and Cockle Creek (direct kokanee and sculpin records) elsewhere in the Duncan system. Best treated as mapping and regulation-confirmation water until a direct survey or field report improves the picture.

Documented food and forage specific to Pat Creek has not been logged. General Duncan Reservoir-edge tributary food, shared with nearby Idaho Creek, typically runs to stoneflies, caddisflies, mayflies, midges, terrestrials and connected-basin fry or sculpin where habitat allows. Where legal and away from any spawning fish, that points to small-stream attractors like Elk Hair Caddis, Adams, Royal Wulff and Stimulator, nymphs such as Prince, Hare's Ear and Pheasant Tail, and a sparse Woolly Bugger or fry/sculpin streamer.

No public road, trail or parking has been confirmed for Pat Creek. Confirm public access, road or trail condition, and tenure on the ground before planning a trip.
