Confirm the current BC freshwater fishing regulations (Region 4 – Kootenay) before you fish; this water is part of the Columbia River system.

It flows into columbia river within the Upper Arrow Lake watershed (Upper Arrow Lake → Columbia River). It runs stream order 5 (well down the network, toward river scale; the scale runs from 1 for a headwater trickle to 6+ for a river) and roughly 23 km. brook trout, bull trout, kokanee, rainbow trout, recorded here in provincial fish-inventory data (36 records). The fish-passage model expects Westslope (Yellowstone) Cutthroat Trout here too, since the reach is reachable with no barrier between, though there is no direct record yet. Named tributaries: Sob Creek.

For an angler judging whether the fishing is worth the drive, the stocking record is the fishing report. St. Leon Creek is a put-and-take angling fishery, stocked with catchable game fish: 8 recorded releases totalling 38,591 fish (Bull Trout, Rainbow Trout), last stocked 2000-07-20.

Stocking appears to have wound down after 2000. Confirm whether it is still topped up or now fishes as a residual, wild population. The chart below shows the full release history.

As a small stream, a tributary of Columbia River, St. Leon Creek fishes the way creeks of its size do: short drifts with a buoyant attractor dry over a light dropper, working the pocket water and the heads of pools. The stocking record below is the truest read on what you will catch.

Access for St. Leon Creek, meaning the roads in, put-ins and any walk-in or seasonal limits, is worth confirming locally before you commit a day. The drainage map shows how the water sits in its valley.
